Unless your machine is branded as vPro it most likely means that it simply lacks the FW part to run AMT. So it will have the ME in the chipset, it might as well

Unless your machine is branded as vPro it most likely means that it simply lacks the FW part to run AMT. So it will have the ME in the chipset, it might as well have the correct CPU and NIC for vPro (usually the NICs with M for management in the model name), but it's missing the firmware. Outside of OEM machines the only time I managed to build a vPro enabled system was in Haswell times when Intel had desktop motherboards with the correct chipset and NIC combination, and the BIOS to run it. Right around that time Intel exited the motherboard business and most manufacturers don't bother with shipping the firmware anyway.
