Check the OEM's manual. There are nearly always options in the BIOS to disable. Also Intel's AMT engine rolls by during POST. You can do a <Ctrl-P> to go into the AMT (not BIOS) settings to see provisioning status and/or reset the ME AMT configuration in all cases I've seen.

On really old or some oddball systems the process requires a CMOS battery pull for a few minutes.

This all assumes your device was enterprise targeted to start with. If it lacks vPro/DASH it's irrelevant.

You can double check your own device in other ways too like seeing if there is a web server at http{s}://your_local_ip:{16992,16993}/ (from another host on your LAN not the same one).
