Then you have no need in zfsboot, you shoud use gptzfsboot instead.
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ad8
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ad10
This will install Protective MBR to first disk sector and bootcode to
first partition. You can backup them just-in-case or update one disk and
try to boot from it leaving second as the known to work solution.
