I installed Proxmox on an older computer (AMD with DDR3), and in it Home Assistant OS. The network interface was called en01. Everything worked great.
After changing the computer to Lenovo ThinkCenter M910q, the network interface was called enp0s31f6 and after installing everything again (Proxmox + HomeAssistant OS as VM) in HAOS (during start) I getting a error:

"FAILED to start Network Manager Wait Online"
I tried installing HAOS using Proxmox Help Scripts, and manually creating a VM.
I added other network cards to USB.

The error always remained.

Finally, I installed Home Assistant OS directly on the computer and without changing any settings in the network it works correctly.

There are several threads on the forum about this error. But not when working with HomeAssistant which uses Network Manager and this error prevents the use of HA.
I would love to use this mini pc with Proxmox and HA + other services, because ot its efficiency - it take 7W now.

Maybe someone has encountered a similar problem.

Best regards.
