I'm sorry, I don't really understand 🙁 Does this mean I need to use the code with the pre_get_query? Where does it go?
(I'm not that pro 😉 )

Hello,

For multiple post views, you can setup the custom codes as below:

add_filter( 'wpv_filter_query', 'display_not_exist_posts', 99, 3 );
function display_not_exist_posts( $query_args, $view_settings, $views_id  ) {
    if ( in_array($views_id, array(123, 456, 789)) ) { // if it is specific view and by default
        $query_args['meta_query'][] = array(
                'key'     => 'wpcf-hide-me', 
                   'compare' => 'NOT EXISTS',
        );
    }
    return $query_args;
}

Please replace 123, 456, 789 with your post view's IDs

For WordPress Archive, you can use pre_get_posts action hook like this:

function WA_display_not_exist_posts($query) {
  if( !is_admin() && $query->is_main_query() && is_post_type_archive( 'movie' ) ) {
    $query->set( 'meta_query', [
      [
       'key'     => 'wpcf-hide-me',
       'compare' => 'NOT EXISTS',
      ],
    ]);
  }
}
add_action( 'pre_get_posts', 'WA_display_not_exist_posts', 99 );

Thank you! This was super clear and helpful. The views worked great out of the box, and for archives I only had to remove the && is_post_type_archive( 'movie' ), looks like for regular posts this is just not needed at all.
