Ok, I manage to do it with the 2 filters. If anyone is interested:

$single_price        = wc_get_price_excluding_tax($product, array(‘qty’ => 1));    $row_price = (float) $single_price * (float) $quantity;

function crew_b2b_prices_rounding($price, $qty, $product) {
    $price = number_format($price, wc_get_price_decimals()); //returned format must be 0,08. No extra digits after.
    return $price;
}
add_filter('woocommerce_get_price_excluding_tax', 'crew_b2b_prices_rounding', 10, 3);

function subtotal() {function crew_b2b_product_subtotal_rounding($product_subtotal, $product, $quantity) {
if ($product->is_taxable()) {
if (!WC()->cart->display_prices_including_tax()) {
$single_price        = wc_get_price_excluding_tax($product, array('qty' => 1));
            $row_price = (float) $single_price * (float) $quantity;
            $product_subtotal = wc_price($row_price);
}
}
}
add_filter('woocommerce_cart_product_subtotal', 'crew_b2b_product_subtotal_rounding', 10, 3);

function crew_b2b_cart_totals_rounding($cart) {
function crew_b2b_prices_rounding($price, $qty, $product) {
    $price = number_format($price, wc_get_price_decimals()); //returned format must be 0,08. No extra digits after.
    return $price;
}
add_filter('woocommerce_get_price_excluding_tax', 'crew_b2b_prices_rounding', 10, 3);

function subtotal() {function crew_b2b_product_subtotal_rounding($product_subtotal, $product, $quantity) {
if ($product->is_taxable()) {
if (!WC()->cart->display_prices_including_tax()) {
$single_price        = wc_get_price_excluding_tax($product, array('qty' => 1));
            $row_price = (float) $single_price * (float) $quantity;
            $product_subtotal = wc_price($row_price);
}
}
}
add_filter('woocommerce_cart_product_subtotal', 'crew_b2b_product_subtotal_rounding', 10, 3);

function crew_b2b_cart_totals_rounding($cart) {
    if (!$cart->display_prices_including_tax()) {


        $subtotal = 0;
        $taxes = 0;
        $tax = new WC_Tax();

        $price_includes_tax = false;
        $product_taxes = array();

        foreach ($cart->get_cart() as $cart_item_key => $cart_item) {
          
            $product_subtotal = 0;

            $product_id = $cart_item['product_id'];
            $product = wc_get_product($product_id);
            $single_price        = wc_get_price_excluding_tax($product, array('qty' => 1));
            $quantity = $cart_item['quantity'];
            $product_subtotal += $single_price * $quantity;
            $cart->cart_contents[$cart_item_key]['line_subtotal'] = $product_subtotal;
            $cart->cart_contents[$cart_item_key]['line_total'] = $product_subtotal;
            if ($product->is_taxable()) {

                $tax_rates = $tax->get_rates($product->get_tax_class());
                $subtotal_taxes = WC_Tax::calc_tax($product_subtotal, $tax_rates, $price_includes_tax);

                $subtotal_tax = array_sum($subtotal_taxes);
                $cart->cart_contents[$cart_item_key]['line_tax_data']['subtotal'] = $subtotal_taxes;
                $cart->cart_contents[$cart_item_key]['line_tax_data']['total'] = $subtotal_taxes;
                $cart->cart_contents[$cart_item_key]['line_subtotal_tax'] = number_format($subtotal_tax, wc_get_price_decimals());
                $cart->cart_contents[$cart_item_key]['line_tax'] = number_format($subtotal_tax, wc_get_price_decimals());
                $taxes += $cart->cart_contents[$cart_item_key]['line_subtotal_tax'];

                //set product taxes here
                foreach ($subtotal_taxes as $key => $value) {

                        $product_taxes[$key] += $value; // Add to existing key
                    } else {
                        $product_taxes[$key] = $value; // Create new key
                    }

        $cart->set_total_tax($taxes);
        $total_tax = $cart->get_total_tax();      
        $discount = $cart->get_discount_total();
        $discount_tax = $cart->get_discount_tax();
        $total_discount = $discount + $discount_tax;
        $cart->set_subtotal($subtotal);
        $cart->set_total($subtotal + $total_tax + $shipping_total + $fees - $total_discount);      
    }
}
add_action('woocommerce_after_calculate_totals', 'crew_b2b_cart_totals_rounding');

I’ve manage to solved it by myself

<select name="category_name">
		<?php
			 $terms = get_terms( 'category' );
			 $count = count($terms);
			 echo "<option value=''>All</option>";
 if ( ! empty( $terms ) && ! is_wp_error( $terms ) ){
     foreach ( $terms as $term ) {
				echo "<option ".selected( $_GET['category_name'], $term->name )." value='$term->name'>$term->name</option>";
			}
		}
		?>
	</select>
