Netplan dying on VM

I am running PVE v7.7-1 with a VM running ubuntu 18.04.4.

I encountered weird errors regarding my networking interface on the VM when I tried to restore from a snapshot. The networking configuration was working fine at the time of the snapshot, and before the restore. I am seeing weird errors in dmesg, and netplan decided to crap out immediately after I tried to restore from the backup. I am doing PCIE passthrough of the NIC card directly to the vm, never had an issues with it before.

So I have a question: I want to install NetworkManager to see if that will fix the weird networking issues, the issue is it's not installed already, and the VM has no internet access. Is there anyway I can mount a median with the .deb file on it and use that to install NM?

dmesg | grep -e ixgbe -e enp
