Not familiar with the Switch 2’s eventual region locks, but are those still a thing? On Switch 1 at least, you just had to change your account region in the settings in some browser, no questions asked. Though it wouldn’t be the first time Nintendo does console 1 without geoblocking, console 2 with geoblocking, and console 2’s backward compatibility without geoblocking (DS & 3DS being the first case).



But some consoles are modded, that’s for sure. Perhaps that would allow investigating further exploits.
Still, console modding that depends on services provided by those not interested in the modding, like the company behind the console itself, is generally not long-lived. So looking at how modding in this era of services usually goes, I’d suggest keeping yours offline, and on the lowest firmware version (“system version”) you can.
At worse, put it online to download the patch for supporting physical Switch 1 games if needed, and figure out how to remove the nagging update message that will keep appearing afterwards (maybe the safe boot option like with the Switch 1 would work?)
