I have a Nintendo Switch, I've literally never used it to play a game where cheating is a concern. Cheating in games is not a crime and it's not worth bricking devices to avoid.
I'm glad your experience has been fine. That doesn't mean that everyone has the same experience. Cheating in games can easily become criminal, and people have been arrested for doing so. Even though cheaters are often not prosecuted, these activities can often amount to fraud or hacking.
