A quick update, as a tempory fix to stop yith gift cards being added via the coupon field i have added the following code to mark them as invalid.

/**
 * Stop gift vouchers from being entered in the coupon form
 * 
 * @param boolean $valid 
 * @param \WC_Coupon $coupon 
 * @return boolean 
 */
function disable_yith_gift_cards_being_entered($valid, $coupon)
{
    if ($valid) {

        $code = $coupon->get_code();
        $query = new \WP_Query([
            'post_type' => 'gift_card',
            'name' => $code
        ]);

        if ($query->found_posts > 0) {
            return false;
        }
    }

    return $valid;
}

add_filter('woocommerce_coupon_is_valid', 'disable_yith_gift_cards_being_entered', 10, 2);
