The only reliable way to "remove all of the spyware" from your
firmware - is to switch to the opensource coreboot BIOS with as few
binary blobs as possible. (By simply removing some UEFI modules you
could't guarantee the security, I hope you understand this). If your
PC isn't supported by coreboot: either try to port a coreboot to it if
it's possible, or sell it and buy a supported PC with that money.
