This is a great thing. We are working hard and hope that the result is good.Seems that way here too, it was good to have them for a more complete map.
I only tested 15,1 SMBIOS with multiple displays in UMA without MXM card in Mojave, so you may be right and in Catalina+ external displays may not work using this SMBIOS. I will change for my following tests.
I'll build a couple more SSDT's tonight to have a complete map of all possible acpi variables. I think we're on the right track, these results so far look very promising.

On the left are MXM card populated, and on the right without.
(For example I really like HVCO, that on both of my tests show 0x1, but on all of yours show 0x4, so this could be displays patched to IGPU?) Will still have to read a lot, but having this info is very valuable.
I'm starting to get a better understanding of how everything must be connected. If I'm right and there are ACPI triggers, we'll be able to flip the switches.
What I want to solve is that an external monitor can be installed when the independent display is installed, but the current SMbios 15.1 mac model we are using cannot directly output, even in UMA mode, it is not possible to externally display dual-monitor output. I think we need to solve him problem by problem. Hope the ending is good.
