@Shafiro - a 12th gen metalbox running only HAOS directly would be (way) under-utilized. As such would recommend a slightly different approach to the above: Install proxmox on the metal, and use proxmox for VM and containers.
Installing Home Assistant OS using Proxmox 7 - Community Guides - Home Assistant Community (home-assistant.io)
tteck/Proxmox: Proxmox Helper Scripts (github.com)
… so that you get best of both worlds.
I have read it somewhere that people successfully put frigate in a linux VM, in Proxmox, with Coral pass-through.
