Block Network Access for Game?

I know there are some tools including firejail and bindtointerface on standard Linux Distros, but they don't run in userland, so whenever the deck updates they will be overwritten.

Anyone have any ideas how to block access on a Steam Deck?

Uh, under Windows use NetLimiter. Under Linux? Try AppArmor based policies, otherwise... No idea.
- Hmm, I wonder if SteamOS has AppArmor by default so I can tinker with it.
  
  IIRC it is based on Ubuntu, so yes.
Doesn't flatpak use bubblewrap for it's permissions? Otherwise would those programs work in distrobox?
- I read an earlier Lemmy post where someone suggested setting the WINE proxy settings to some invalid setting for the game as a work around. I need to test it and see if it works.
Have you tried OpenSnitch
- Thanks for the suggestion, I think the main issue is doing it on the Steam Deck. On a native Linux machine it's easier. I don't see a way to install OpenSnitch on the Steam Deck with the read-only file system and whatnot. I think a pi-hole and block DNS might be easier than trying to mess with SteamOS.
  
  You can't install applications on steam deck and there is a read only file system???? Whaaaatttt???????
  
  Edit: I asked a friend that has a steam deck, he explained you can easily disable the read-only system, do whatever you want on a Linux system and reenable it afterwards.
