All EFI needs is an valid EFI partition on a GPT disk and the updated
loader.efi so if your devices is GPT based and you have space for an
extra 800k partition then yes.
The following should be the basic steps you need (untested so backup
your data)
1. gpart add -t efi -s 800k <dev>
2. gpart bootcode -p /boot/boot1.efifat -i <idx> <dev>
3. Ensure your root filesystem has EFI ZFS boot compatible world e.g.
cd /usr/src && make buildworld -jXX && make installworld
If you have an active MBR then you will likely need to disable this as
EFI seems to ignore disks with active MBR even if they have a valid EFI
partition.
If you don't have space then you'll need to migrate to a difference
device to change the disk partition layout.
