Graphics drivers, at least on unices, come in two parts: one in the kernel, another one in the userspace. The latter provides interfaces such as Vulkan. That said, ANV (Intel's driver) is part of mesa, and not bespoke like nvidia's. But that's a moot point: this telemetry component is not a part of the actual driver, but another separate program in the package.
I do use the full fledged nvidia drivers on linux (I don't know if with the mentioned libre drivers the steam games, LLM's and image generation I use would work?), so I would also like to know if this telemetry is also present in the linux drivers
