Can I change the default permissions of Unity NFS FileSystem?

By default, permission of Unity NFS filesystem is root/755, so non-root Pod cannot write the data when using Unity NFS PVC.

Generally, the permission can be changed by chown and chmod using initContainer, but the permission cannot be changed through initContainer due to the Security Context Constrain (SCC) in the Red Hat Openshift environment.

Is there any other way to change the permissions of the Unity NFS file system without initConatiner?

For reference, I think the permissions of unity nfs filesystem should be 777 in Kubernetes environment by default. The NFS permission of Isilon and PowerStore is 777.
