Exactly what at the end did

class YoastUpdateController extends WP_REST_Controller {
	public function register_routes() {
		register_rest_route( 'wp/v2/', '/action/', array(
			'methods'  => 'GET',
			'callback' => [$this, 'update_yoast_meta']
		));
	}

	function update_yoast_meta($data) {
		$postID = $_GET['postID'];
		$metadesc = $_GET['metaDesc'];
		if ($postID && $metadesc) {
			$this->add_to_yoast_seo($postID, $metadesc);
		}
	}

	function add_to_yoast_seo($post_id, $metadesc){

		$ret = false;
		$updated_desc = update_post_meta($post_id, '_yoast_wpseo_metadesc', $metadesc);
		if($updated_desc){
			$ret = true;
		}
		return $ret;
	}
}

function register_yoast_update_controller() {
	$controller = new YoastUpdateController();
	$controller->register_routes();
}

add_action( 'rest_api_init', 'register_yoast_update_controller' );

This is the only way that i found in order to append via API the metaDesc
