The following commit: 1fea9ddb4e3f OvmfPkg: execute option ROM images regardless of Secure Boot sets the OptionRomImageVerificationPolicy to ALWAYS_EXECUTE the expansion ROMs attached to the emulated PCI devices. A expansion ROM constitute another channel through which a cloud provider (i.e hypervisor) can inject a code in guest boot flow to compromise it. When SEV is enabled, the bios code has been verified by the guest owner via the SEV guest launch sequence before its executed. When secure boot, is enabled, lets make sure that we do not allow guest bios to execute a code which is not signed by the guest owner.
