There is no prescribed way to disable it, and it looks like the slides only provide a glimpse of the workarounds/hacks needed to do so. I imagine there's a lot we're missing from this presentation, though, because it looks like there was a demo.

The demo is also available in the repository. https://github.com/ptresearch/me-disablement/blob/master/Int...

Only for relatively old models, see https://libreboot.org/faq/#intelme.
