Cheat engine do's and do not's

I've already beat Elden Ring, so now I want to use cheat engine (hexington) to mess around with the game a bit, but I also don't wanna get banned from online play, i know to run the game in offline mode and all of that but i know the game checks some stuff that can still get you banned (editing runes is the only one I know of)

also if I use nodead in offline will that get me banned when I switch back to online?
