If you didn't install NSP on official NAND so you should be safe - not banned and Atmosphere has protection against telemetry and error reports from send to Nintendo. Do everything with emuMMC is safe as long as you don't go online.
Hey hi i'm gonna bounce on your quote for asking a related question but "doing everything in the emunand is safe as long as you don't go online" it is true we can play our legits games on the emunand and edit the saves/modding the game ? I'm thinking about super smash bros ultimate, pokemon shield and taiko no tatsujin I own and I want to get the dlcs/modding on my emunand but of course I don't want anything of this to touch my sysnand real save/content
