Change owner NFS Volume

Hi people, I trying to change the owner of a mount point but in the pod shell I see this error:

chown: changing ownership of ‘/var/www/upload’: Operation not permitted

drwx------ 2 1001 1001 6144 May 9 16:26 /var/www/upload/

I thought that using the root user id in the securitycontext would be able to do it but it does not work:

spec:
  terminationGracePeriodSeconds: 60
  containers:
    - name: test-sftp
      securityContext:
         runAsUser: 0 
      image: xxxxxxx.dkr.ecr.us-east-1.amazonaws.com/testsftp:x.x.x
      command: ["sh", "-c", "chown 0:0 /var/www/upload"]
      imagePullPolicy: IfNotPresent
      ports:
        - name: test-sftp
          containerPort: 2222
          protocol: TCP
      volumeMounts:
        - name: efs
          mountPath: "/var/www/upload/"

I have tried, I understand that the root user ID is 0, I tried using it but it does not work:

securityContext:
fsGroup: 0

Any helps?
