For a desktop network manager does the magic. It sets things up for netplan, the yaml file is the netplan config file.
But server does not use network manager because it is CLI only and NM is gui. It does us something called Subiquity to set the network stuff up, but once done it appears that you have to go in and manually modify the yaml file and then tell netplan to try it. If it flies you tell it to accept it. Ought to be some way to tell subiquity to rescan the network cards and add/remove what is there or not.
