Hi,

I am very sorry for the late reply, we did not work on the weekend.

Sure, you can achieve that by adding the following snippet in PHP.

function filter_woocommerce_catalog_orderby( $array ) { 
    unset($array['menu_order']); 
    unset($array['popularity']);
     return $array; 
}; 
add_filter( 'woocommerce_catalog_orderby', 'filter_woocommerce_catalog_orderby', 10, 1 ); 

This is the list:

// [menu_order] => Default sorting
// [popularity] => Sort by popularity
// [rating] => Sort by average rating
// [date] => Sort by newness
// [price] => Sort by price: low to high
// [price-desc] => Sort by price: high to low

The code can be added at the bottom of functions.php in the child theme or via the plugin PHP Snippets.
