This is not needed. It will be better if you forget this option.

In your case you only can write pmbr using gpart(8):

# gpart bootcode -b /boot/pmbr ada0
# gpart bootcode -b /boot/pmbr ada1

Then you can write gptboot to the mirror using dd(1):

# dd if=/boot/gptboot of=/dev/mirror/boot

You can't write gptboot to the partition using gpart(8) because it is
exclusively used by geom_mirror.
