I think the simplest answer to all of this is a cage match.
Specifically, a Faraday Cage.
Magnus believes that Niemann is cheating via communication with a computer. Fine, let's completely remove the ability to communicate with a computer. Both men are searched on the way in. Heck, for fun lets have them play in tight sporting outfits so it's very clear what they are carrying and doing.
If Magnus destroys Niemann, he'll be able to pretty handily claim that Niemann can't win without communication to computers. If Niemann is competitive, or wins, it will be hard for Carlsen to make any more such claims.
And also, the sport will have a spectacle like we've never seen before. Tell me you wouldn't pay to watch that match!
