How to ommit authentication with default/info/home page URLs in keyclock 18

In key clock version 3 we avoid writing “auth-constraint” for default URLs to skip authentication. But in key clock 18 it is not working. Can you please share the parameter or code by which we can avoid authentication for default URLs like info/homepage/dashboard?

This issue come only with those API having Authentication with different user and usage of resource, permission, and policies has been done.

Note:- We are using user based authentication usage of Resource, permission and policies has been done.
