NFS persistent volume is not deleted even with "Delete" persistentVolumeReclaimPolicy

I am using NFS Persistent Volume to create PV.

The reclaim policy being used in persistentVolumeReclaimPolicy: Delete.

apiVersion: v1
kind: PersistentVolume
metadata:
  name: pv001
spec:
  capacity:
    storage: 3Gi
  volumeMode: Filesystem
  accessModes:
    - ReadOnlyMany
  persistentVolumeReclaimPolicy: Delete
  mountOptions:
    - hard
    - nfsvers=4.1
  nfs:
    path: /
    server: fs-0bb.efs.us-east-2.amazonaws.com

However, when I delete my deployment-controller and also delete PersistentVolumeClaim, the NFS volume is not getting deleted.

Expected Behaviour: The NFS PV volume should be deleted after PVC is deleted.

For dynamic PV you just need to delete the PVC and then the PV will be released. From the manifest file you have provided it seems that you are using static PV, so you need to delete both PVC and PV.</span></p>
