Hi, 

I don't know of a way with make release

Briefly, the way I do zfs on amd64 vm is (given you're already set up on bhyve):

a: truncate -s 64G filename.img
b: sh vmrun.sh -c 4 -m 32768M -t tap1 -d filename.img -i -I
freebsd-installer.iso vmname
c: run through the installer, selecting auto-zfs on the way.
d: stop the reboot, run the vmrun.sh again and omit the -i -I 
freebsd-installer.iso bit

(in my context, vmrun.sh is a symlink to
/usr/share/examples/bhyve/vmrun.sh in the dir i'm working in)
