Disable Finder browsing of zpool?

I am using my Mac as a backup host for an Illumos-based server, saving ZFS snapshots on external hard drives. However, I'd like to avoid Finder trying to browse the files. Is there a way to do this cleanly?
Because you care about your data.

com.apple.browse=on | off
Equivalent to mount option browse/nobrowse. This option indicates
that the mount point should not be visible via the GUI (i.e.,
appear on the Desktop as a separate volume). Setting it to off will
result in Spotlight being unavailable for the specified mount
point.
