Indeed, these are contradicting requirements. The RNG detection, as outlined by Intel documentation, requires being able to write to firmware hub space (which in turn is hidden behind BIOS space). But I agree that this is not a good solution (and even without that, it is not good to require temporarily making invisible the entire BIOS code/data in order to detect a non-essential device like an RNG).
