There are some 3rd party programs that actually improve features that people have asked for for years
Like a motion sickness camera & settings add-on that isn't even in the game.
There are some in-game work arounds but they hardly help.

I do not want an anti-cheat rootkit digging around my PC.

A good way to keep people from cheating is just punish them- take away their rewards & prestige when caught & enact perma bans.
