Yes, this can be done (on an unmounted fs) using:

  gfs_tool sb <device> proto lock_dlm

Note that you better should add enough journals to the filesystem
when creating it.  You can add journals later, but only if there
is (enough) space left on the device after the filesystem, which
is normally not the case (if your filesystem occupies the whole
device).
