> there's no part of the boot firmware that continues interacting with any NIC after the OS has taken over managing PCIe peripherals Are you sure about that? Because I remember something called ACPI that gets executed by the OS every time some configuration changes, such as power levels.

  I'm not that knowledgeable, but I rememember Computrace auto-install on a system that didn't even have UEFI.
