Hi,
there are a few things you should be aware of:
Changing the hardware layout might lead to renaming of network interface names, following systemd's predictable name scheme as described here [0]. So you will have to check that the interface names did not change after adding the card or explicitly define .link files to statically name network links [1].
Also, depending on the NIC you will have to install additional drivers if they are not available via the Proxmox VE kernel and you will have to configure the new interface in /etc/network/interfaces.
