How to hide a page in wordpress made for menu

Just create a custom template template-redirect-home.php and assign it to that page and redirect to homepage on load with sth like this:

add_action( 'template_redirect', function(){
  if(is_page_template('template-redirect-home.php')){
    wp_safe_redirect( get_home_url(), 301, '');
  }
});

You can also use Custom links in the menu to not access the page directly from the menu.
