If you really want to play games with anti-cheat with a Linux machine right now you could also try cloud gaming, or to be exact Nvidia's Geforce Now - because most of the smaller cloud gaming services like Shadow PC and Boosteroid simply run Windows Virtual Machines with GPU passthrough on which kernel level anti cheat... you guessed it... does not work.
Nvidia is publically advertising that five games from the Call of Duty series (notoriously known for their kernel level anti cheat) and Battlefield 1, 4, 5, 2042 and the very recent Battlefield 6 (same) are able to run on Geforce Now (https://www.nvidia.com/en-us/geforce-now/games/).
There's even a native client for Linux thanks to their recent Steam Deck support (you only need to hack a bit since it's basically optimized to run on SteamOS KDE and Steam Big Picture mode which is quite easy thanks to Google search, and you should be pretty much good to go).

Another option would be Moonlight/Sunshine (https://moonlight-stream.org/, https://github.com/LizardByte/Sunshine) but that option requires you to have a pretty beefy game PC or server w/ decent GPU next to your Linux machine to host the games.
