Hi @kastl-ars
Thank you for this. LGTM
Due to my recent merge, we did add rbac like this which we would want to consider upon. My bad here, I should have seen it under my PR.
Should we also have them under this if condition too, we are already gating them under a helm config?

Question is do we also want to have rbac.enabled flag gate the cluster role needed in openshift environment too (that looks exactly what this flag is intended to do) or we can have scenarios where a user wants to disable the rbac.enabled flag but want the required cluster role, etc for openshift environment.

Otherwise the Issue raised and PR is really helpful
