Is it possible to do so on the fly, or is it better/required for the filesystem to be quiesced first? We are using Lustre 2.10.7 with ZFS 0.7.5 (project quotas are not needed).

You should be able to enable enforcement on the fly by using the “lctl conf_param” command (something like "lctl conf_param <fsname>.quota.ost=ugp”).  The Quota chapter in the lustre manual explains in more detail.
