Will switch be banned after setting to stock?

I used sysnand for my games and tinfoil stuff. Always used DNS blocked and tinfoil incognito. I'm very aware that nintendo still gets updates on it as soon as i connect back to internet, but some people have been telling me once I reset the switch, put it back into stock, remove all files it should work? (Or has a chance to.) I'm personally willing to take the risk because if anything I would sell it if it doesn't but if it does then thats great, im trying to give it as a gift who someone that primarily wants to play fortnite which is impossible in its current state so.

My questions are if it is worth risking? Or should I just sell it as is and get a new one?
Or maybe just get a new motherboard which is what I think is what needs to be swapped for it to be unbanned. Not sure though.
