I'm not exactly an expert either, but as far as I know there's nothing stopping you from modifying your own kernel on Linux if you're a hardcore enough Linux dork who knows how to. This is part of the reason anti-cheat developers love Windows and hate Linux, the Windows kernel is practically considered a black box that no normal user is ever supposed to touch, and Microsoft tries reasonably hard to make sure it isn't (I had to disable Secure Boot and virtualization in my bios, and add a sketchy looking second boot option to the Windows Boot Manager, back when I paid for cheats in games). This doesn't really work (as evidenced by the existence of kernel level cheats), but that's the philosophy.
On Linux, there are no "normal users". Some people run Arch for fun. Some people run Gentoo for fun. It's the Wild God Damn West. Ergo, you can say "well the kernel will have this functionality built in", and that's all fine well and good -- but there is nothing stopping someone else from coming along, yanking it out (or better still, modifying it to always pass "yep no cheats here" to any anti-cheat, even when there are), and recompiling their own kernel; because the design philosophy in Linux (for the most part) seems to be that the meatbag sitting at the keyboard is God, not some corporation. Which, considering how Microsoft is enfuckening Windows, I consider a good thing.
Kernel anti-cheat is a bodge, a stopgap, a last-ditch effort to save money instead of hiring staff that actually give a shit about supporting a game for people who've already parted with their money and moderating it properly. You know the only games I was never able to cheat in/didn't see many cheaters in/didn't ever really want to cheat in, for that matter? The games where the developers actually gave a shit, made a good game that didn't exploit the player, and paid moderators to do a good job keeping it free of other shitheads. Kernel anticheat wasn't even a speedbump, not then and I doubt it would be now. It's a shortcut taken by lazy and/or greedy companies who would rather compromise user security and eke out a few more percentage points of net profit up-front instead of investing in the long-term health of their community.
disclaimer: I am not a hardcore linux dork. I like Linux Mint nowadays and have for the past couple years because it just works and doesn't give me shit. I could be wrong, but that's the gist of it as it is understood by me.
That sounds like a fine way to have your (presumably expensive) drone carrying your (presumably also expensive) camera hit with buckshot.
I'm not saying don't try anyways. But there's a good chance the gestapo just starts blastin'.
