custom login url

To implement the security of my websites I impost the change of the login url (so I block wp-login.php and manually set the url) via wp cerber.
The problem is that for certain sites with users I have to make a custom login form, and printing the address with the wp_login_url () function, in fact, it becomes public.
Is it possible to use a login address only for the admin (and therefore the standard WordPress login form) and instead, another address for other roles?

So:
https: // mysite / [url set on wp cerber) which allows only the administrator login from standard WordPress form

<form class=”myform loginForm” method=”post” action=”<?= wp_login_url(); ?>”> which returns a different URL from the one set on WP cerber that allows me to log in only as a role non administrator?

Doing so, the public login url does not allow access to the admin panel and the url imposted in wpcerber remains secret.
