Customize 404 error page but not only the view

I'm trying to customize the 404 error page but the only way I've found is to edit the Routes.php file in the Config folder like so:

PHP Code:

$routes->set404Override(function () {
    return view('pages/my404');
}); 


In this way, however, I have no control because I do not have a Controller and Model (if necessary), but only a view.

Is there a way to switch from the Controller and not directly from the view?
