Rancher Permision set

I have a question about Roles in Rancher.
I use Rancher v2.8.0 deployed on k3s and have a few imported kubernetes clusters.
Problem is with user permision.
My goal is to set access only to specific created projects with minimal possible permision.
I make this using built-in roles but something bother me:

There is an option to hide or disable visibility of " Cluster and Project Members"
I want this because now any user cant get there and search users from AD and see their logins.
