How to make network dynamic or sticky ens/enp interfaces on the config file for the bridge?!

Working on some headless deployments.

During the installation I'm using external gpu for the configuration but once completed and gpu is removed the network ID (enp/ens) changes so you are no longer able to access the system.

/etc/network/interfaces by default for default vmbr0 got manual pointer to the physical interface ID (enp/ens) - is there a way to make this sticky so the network ID doesn't change OR make the interface in the configuration file to be dynamic during any physical changes like removal/add of GPU?!

Two pointers we have are iface <interfaceID> inet manual && under the vmbr0 points bridge-port to <interfaceID>

auto lo
iface lo inet loopback
iface enp5s0 inet manual
auto vmbr0
iface vmbr0 inet static
bridge-ports enp5s0
bridge-stp off
bridge-fd 0


I mean you could potentially try blindly go in and change iface enp number and save but thats pain since I don't know whats the new enp pointer after GPU is removed.

Thanks in advance for any advice on this one.
