How to Restrict All Project Roles to Access Only Specific Namespaces in Rancher

Does anyone know how to restrict all project roles so that they can only access specific namespaces? In my current Kubernetes cluster, I have the following namespaces: development, uat, and production. I would like to configure it so that all users, except for myself, can only access the development and uat namespaces, but not the production namespace.

Is there a way to set role-based access control (RBAC) to achieve this? I want to ensure that users are restricted to only certain namespaces for security and management purposes.

Thank you!
