Is there a relatively simple way to block network access to a program? Avoiding the command line ideally.

Heroic Launcher has a “run game offline” toggle for games that are installed/added through it, but I am trying to cut out the middle man and install non-steam games directly through Steam.

Steam launch commands? Any built in firewall?

Thanks in advance!

    Haven’t tried it on Deck, but iptables can do a per-uid based rule which I’ve used in the past

    I.E. login+run restricted games under a particular login, OR sudo to that user for running but allow X-forwarding+PulseAudio to my current login
