Just checked some binaries - PEI USB driver is loading anyway, no
checking for any setup option, so I guess it will be very hard even
with the unpacking UEFI image and removing these drivers. Also in most
UEFI systems big part of USB driver working in SMM mode, so it will be
hard to patch this code on the fly.
