If your root/boot filesystem is zfs then you won't be able to unload the
module.
If your root/boot filesystem is nfs or ufs then you can unload it like this:
svcadm disable -t fmd
svcadm disable -t sysevent
pools="`zpool list -H -o name`"
for p in $pools ; do
zpool export $p
done
sleep 5
modunload -i 0
modinfo | grep zfs
If you do NOT see any output from modinfo then the unload succeeded
if you DO see output from modinfo it did not succeed.
