Bhyve
Nanos works on Bhyve with some caveats:
Nanos uses ELF files so this support is intended more to run Nanos images not necessarily build them since the default file format on FreeBSD is a.out.
You must build Nanos from source with UEFI support:
make ENABLE_UEFI=1
This was tested on FreeBSD 13.6.0.
Install bhyve firmware:
pkg install sysutils/bhyve-firmware 
Create a tap/bridge:
# ifconfig tap0 create
# sysctl net.link.tap.up_on_open=1
net.link.tap.up_on_open: 0 -> 1
# ifconfig bridge0 create
# ifconfig bridge0 addm em0 addm tap0
# ifconfig bridge0 up
Create/run a Nanos VM:
# bhyve -AHP -s 0:0,hostbridge -s 1:0,virtio-blk,./disk.raw \
  -s 2:0,virtio-net,tap0 -s 3:0,virtio-rnd -s 31:0,lpc \
  -l bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd \
  -l com1,stdio nanos
To stop the VM:
killall bhyve
When building with OPS include the UEFI loader in your config.json:
{
  "Uefi": true
}
