Oh, now I remembered that there’s ActivationPolicy= on [Link] that can be used to control what happens to the interface. At some point I even reported a bug on that feature and vlans.

I thought it had something to do with the interface having an IP (…) LinkLocalAddressing=ipv4

I’m not so sure it is about the interface having an IP… I believe your current LinkLocalAddressing=ipv4 is forcing the interface to get up since it has to assign a local IP. Maybe you can set LinkLocalAddressing=no and ActivationPolicy=always-up and see how it goes.
