It would not be much of a stretch at all for nvidia to include their firmware there.
The userspace stack is an issue. For upstream Linux, there’s a fairly hard rule that graphics driver interfaces must be usable with open source userspace. But I don’t think the nvidia graphics user parts are particularly secret, and someone could write such a thing.
