Unmount Job for VMFS

We just successfully tested a RM Job that created a VNX snap clone of a VMFS file system and mounted on a target host.

We now like to create a job that would unmount the VMFS file system from the target host- sync the clone; re-fracture and remount the VMFS file system on the target host.

I do not see an option to unmount for VMFS File System like you would for a normal host.

Is it possible to create a job to unmount a VMFS File System that is currently mounted?

The goal is to resync a VMFS file system daily - and leave the target mounted all day until a re-sync is scheduled.
