That's very easy. With the Switch 1, the usual approach was simply to use a DNS that blocks all Nintendo servers. The problem with that, however, is that a large part of the console’s appeal depends on its online features. On the Switch 2, many games aren’t available as physical cartridges but only as download codes or as cartridges where the module merely verifies ownership, but you still have to download the game. That doesn’t work if you block Nintendo’s server. So you can either use it without jailbreaks entirely or "pirate" all your games.
