BIOS and UEFI bootkits require special vendor tools and vendor signed firmware binaries to overwrite the SPI memory. Standard anti-virus software can not remove them, once they have been installed.

You are right, you patch your bios with a vendor program. However regular virus scanners will detect it and motherboard manufacturers provide bios flashing tools. But AMD has said they will not provide firmware tools for their old CPUs.
