If you are looking for a simple way to remove the “review” tab from the single product view throughout your project you need to add the following snippet to the function.php file of your theme:

 

add_filter( 'woocommerce_product_tabs', 'wcs_woo_remove_reviews_tab', 98 );
    function wcs_woo_remove_reviews_tab($tabs) {
    unset($tabs['reviews']);
    return $tabs;
}
