Sticky Primary Navigation for specific pages?

Ok. This CSS seems to work!!!
Anyway, could you provide me with the code to disable the sticky navigation? I will be able to try both routes and then I will decide. Thank you so much!

We can use this PHP snippet:

add_filter( 'option_generate_menu_plus_settings','lh_turn_off_sticky' );
function lh_turn_off_sticky( $options ) {
    if ( is_page( 554 ) ) {
        $options['sticky_menu'] = 'false';
    }
    
    return $options;
}

I have add your PHP snippet using Code Snippets plugin, as it is suggested in documentation, but it does not work... (I have remove the previous CSS to try it).

Sorry - edited the code above.

Yes. Now it works perfect! Thank you very much!
Only one more question: if I would like to do the same in other page, should I copy-paste changing the page-id or could I add more page-id to that function?
Thank you again. Your customer support service is amazing.
