   Example of Custom Post Type args change via filter hook. Changing rewrite slug from movies to films:

   add_filter('register_post_type_args', 'movies_to_films', 10, 2);
   function movies_to_films($args, $post_type){
   
       if ($post_type == 'movies'){
           $args['rewrite']['slug'] = 'films';
       }
   
       return $args;
   }

   You can also use `register_{$post_type}_post_type_args` to target a specific post type.

   For example, you can use `register_post_post_type_args` to target only the Post post type and modify how it’s registered:

   add_filter( 'register_post_post_type_args', 'wpdocs_default_posts_template' );
   /**
    * Add default template for new Posts with the Featured Image as the first block
    */
   function wpdocs_default_posts_template( $args ) {
       $args['template'] = array(
           array( 'core/post-featured-image', array( 'align' => 'center' ) )
       );
   
       return $args;
   }

   • It should be mentioned that the filter register_{$post_type}_post_type_args is called after the filter register_post_type_args and thus can overwrite possible changes of the first one!
