the new mac mini 8,1 does not configure the IGPU as headless even when used in conjunction with a Thunderbolt eGPU. It is a totally active GPU shows up in system report, it is an option to change to use that GPU instead of the eGPU in games and programs. When setup headless the IGPU almost totally disappears from the system visually.
@scottkendall,
Thanks for your post and the information, the mention of iMac Mini in the note is referring to the old models that had both IGPU and Nvidia GPU's ... I'll up date the note to make that a bit clearer.
With regards to the new iMac Mini 8,X SMBIOS .. what you state makes sense as those systems are not available with a built in dGPU, however despite this Apple have included two headless PlatformID's for Coffee lake desktop systems, these ID's are only available in MacOS Mojave.

As you can see from the above PlatformID dumps both 0x3E920003 and 0x3E910003 are completely headless (0 port count), i don't have a Coffee Lake system to test them with myself but I've helped others with Coffee Lake Systems to configure their systems as headless with these ID's and they have confirmed that they work.
Right now it seems that UHD 630 IGPU does not work well solo on a Hackingtosh, so best to use alongside dGPU and configure as headless.
Cheers
Jay
