If you have a secure and attested boot chain, then anti-cheats can also start depending on things like DMA protection[1] to be enabled or other CPU features to protect against rogue hardware doing DMA attacks. At the professional level tournaments are already whitelisting what hardware is allowed for competitor machines - I doubt that they'll start doing that for the average joe gamer lobbies anytime soon, but they do have the option to start blocking people who have anomalous PCIe DMA mappings etc. and steadily raise the bar.
