Help with HP 8460p "install Intel AMT"

I have a hp 8460p without official intel support for vpro.
Chipset QM67
i5-2520m processor
Embedded video.
There is no discrete video.

In the BIOS itself there is an Intel AMT setup
But the combination ctr+p does not work.

When trying to flash Intel Full Management Engine (ME) Firmware Component from the official website, it says that the function is not supported.


I want to get Intel AMT working on this laptop
At the level of iron should be supported by all, the question of how to flash the BIOS ME
Has anyone encountered such a problem?
