Oh I run Linux as well (Debian) but this is definitely Windows 11. I have been taking ownership of folders to disable updates since Windows 10. I haven't quite nailed down how to do similar in Linux (although disabling updates is easy, I just can't wrap my head around how permissions work in Linux enough to disable Steam updates, so I run it offline only)
Taking ownership and inheriting permissions has existed since NT 4. Windows is just there for the couple of online games I run (PC Building simulator, MS flight sim 2020--the latter of which refuses to run in Linux. freezes hard before the menu shows and fans max out). I had to remove all write permissions and add in some shortcut hacks to the properties just to stop Steam from updating or forcing an update on games to even run them in offline mode. I might go to another platform (GoG, Epic) since I read online that they don't force updates on anyone. I don't believe in updates. Ever since iOS 7 and Android 5, they left a bad taste in my mouth. IF anything gets updated on my stuff, it's my choice, and I must be able to roll back if I don't like it. Steam is making that infinitely harder.
