What are the best ways to run a game on sandboxed mode with only game HDD shared to it. There should not be network access for the game and there should be GPU (intel integrated) pass-through.

I have tried Gnome boxes, but GPU pass through is not working and checked distrobox, but that too shares HOME folder.

Update: I have installed Bubblejail and sandboxed Alacritty. Shared a Directory in with it on Home and disabled network. Since my game is launched using a shell script, I use this setup for it.
