Yes.

You need to put the storage domain in maintenance mode, and then
you can edit the gluster mount options.

This requires either shutting down all the vms using this storage, or
if you cannot afford any downtime, you can live-migrate the disks to
another storage domain, edit gluster options, and live-migrate the disks
back.
