How to set hard on sharedv4_mount_options?

Portworx on Kubernetes
1

I tried to set hard on sharedv4_mount_options.

kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
  name: sc-px-auto-medium
provisioner: pxd.portworx.com
allowVolumeExpansion: true
parameters:
  io_profile: "auto"
  repl: "3"
  priority_io: "medium"
  sharedv4_mount_options: "actimeo=60,proto=tcp,retrans=2,hard,timeo=600,vers=3.0"

The volume created using this StorageClass would be set to both soft (default value) and hard.
