Yes it works, I just tried it using sysutils/vm-bhyve (just add
virt_console0="Yes" to the configuration file).

Based on the logs, these device settings are used by it:

    bhyve devices:
      -s 0,hostbridge \
      -s 31,lpc \
      -s 4:0,virtio-blk,/dev/zvol/zroot/vms/freebsd14-test/disk0 \
      -s 5:0,virtio-net,tap0,mac=58:9c:fc:aa:aa:aa \
      -s 6:0,virtio-console,0=/vms/freebsd14-test/vtcon.0

I could connect to /vms/freebsd14-test/vtcon.0 using socat:

    socat - UNIX-CONNECT:/vms/freebsd14-test/vtcon.0

Inside the vm it's /dev/vtcon/0.
