If you want to mod your Switch 2 by adding custom firmware or homebrew apps, think again, because in Nintendo's End User License Agreement or EULA, Nintendo may be allowed to make your Nintendo Switch digital products "unusable" if you decided to modify the firmware.
I mean, technically yes, if you don't know what you're doing, you might be at risk of bricking the system, but people seem to get the impression that Nintendo is willing to brick your system the moment they detected that you are modding it or jailbreaking it.
Personally, trying to mod or jailbreak a recently released hardware while they are still receiving software updates is incredibly risky and should not be attempted by anyone who isn't an expert. That still won't stop expert hackers from trying to hack the upcoming Switch 2, and that won't stop them to try to find ways around it.
Yet again, this is another installment of Nintendo vs hackers. We'll have to see how that goes in the future.
