Just because it is detected it does not mean a driver is attached to it.
E.g. on my machine:
# pcidump | grep -i mei
0:22:0: Intel 200 Series MEI
# dmesg | grep -i mei
"Intel 200 Series MEI" rev 0x00 at pci0 dev 22 function 0 not configured
The "not configured" is the relevant part, here.
Plus, more knowledgeable people will correct me if I'm wrong, but I
don't think a "mei" driver exists.
If for some reason you want to "disable" it further that this you'll
have to do it in BIOS or find a way to power it off, but good luck with
that.
