Remove any product that is featured from regular display loop [WooCommerce]

Use the pre_get_posts filter to remove your sticked product from the product loop.

add_action( 'pre_get_posts', 'exclude_stycky_product' );

function exclude_sticky_product(){
    // target only the main query
    if ( ! is_admin() && $query->is_main_query()  ) {
         $query->set('ignore_sticky_posts');
         $query->set('meta_value', '1');
    }
}

Hope it helps you !
