Will using CM in the console permanently disable achievements for a server?

[Nef]

I've been searching on Google but there's like 5 years of conflicting information, so asking again in 2020. Some say you can never use CM ever, or you will permanently lose the ability to get achievements, while others say you can freely use CM and they will re-active once it is disabled. I'd like a concrete answer before messing up my server, lol. Got an issue that we can really only fix with CM.

As far as I'm aware, most achievements will re-activate earning once CM is disabled. Others won't re-activate until the server is restarted. There may be one or two that never re-activate though, and there are a couple of achievements that are just plain broken atm.
