alt Hacker NewsFair warning that Nintendo likes to remote-kill both Switch 2 consoles and the game cards used by them once they detect jailbreaks from all future accesses to online services, so you should probably take steps to permanently detach your Switch from all online services and from WiFi before experimenting with this, and expect that selling any game carts from your jailbroken console can land you in hot water with the buyer reporting your info to Nintendo someday. Thanks, secure attestation of burned-in serial numbers! (This was in the news last year iirc? but not so much of interest to HN at the time.)
They can (and will) ban you from online services (the console, not the account). No, they won't brick your console remotely (blown out of proportion from a sentence in the EULA that's there since the Wii days and other vendors also have it)
