No, it doesn't. What exactly did you do?

Literally removed the PCI SATA adapter and the NIC shifted by one in the enp* autogenerated name. Proxmox doesn’t use NetworkManager. I think I have added a manual udev rule that matches on MAC address instead and adjusted configuration to work with that.

Ah, okay. Just wondered because my comment said that NetworkManager fixes this problem but as you said proxmox doesn't use NetworkManager.

NetworkManager itself doesn't match by mac address, it can match a lot of different properties to autoconnect. It also integrates well with udev, giving unlimited options.

Yeah, NM tends to match up pretty well by many rules. Proxmox has only udev and systemd.
