Seems like there might be a private API for this. Maybe it's easier to go the reverse engineering route? Unless it'll end up requiring some special entitlement that you can't bypass without disabling SIP.

There has to be a private API for this; the post says:

How would the Metal profiler be able to do that if not for a private API? (Could some debugging tool find out what's going on by watching the profiler?)

Lol I just read the parent comment without noticing that they were quoting the exact same sentence from the blog! ;-)

Sorry about that!
