Call of Duty Adds Kernel Level Driver for Anti-Cheat

Windows drivers can be loaded and unloaded dynamically, yes. It's also possible that they're using "shut down" semantically and not literally, in that the driver is loaded but inactive while the game isn't running.

Isn't this the case for every major OS? I know FreeBSD device drivers can be (un)loaded on-the-fly. Same for MacOS. I assume it's also possible in Linux(?)

It is. I believe you use

  modprobe -r kernel_module_name

to unload a kernel module and

  modprobe kernel_module_name

to load it.

Linux lets you disable dynamic modules. OpenBSD removed support for them some years ago.

macOS doesn't let you load kexts anymore since it's less important with drivers moving to userspace.
