No. That only works for block devices. NFS does not involve block devices.

No. cgroupsv2 does not support that.

I am not sure if NFS supports what you are trying to do at all, as
traffic generated by NFS is probably not attributed back to a process
and hence a cgroup. You might want to ask the NFS community about
that.
