While I'm on the topic, is it possible to pass a com port through a vm to HA?

My Unraid motherboard has a single serial port on it. I’m wondering if I can just assign that serial port to the Home Assistant VM and then configure HA to use that port to control the RS232 commands to the Monoprice 6-Channel Amp instead of trying to go USB to 232 or Ethernet to 232…

Thoughts?
