I have tried having two TB controllers (I actually tried 3) on the board and it worked no probs, but of course I firmware flashed both (on board and Titan Ridge PCIe AIC cards) with custom CR8, with 0, 1 and 2 bus for the OS to recognize the controllers, besides I had to jump wire pins 3 and 5 from TR AIC cards in order to "turn-it-on", otherwise we would need the TB header which if your board has on board Thunderbolt, won't have the header.Yes, i did not do it because I though you already have checked as you have successfully booted with OpenCore.

It has a much heavier reliance on ACPI, and as a result is much more likely to expose bugs in your ACPI implementation of _PLD, and _UPC. It is covered in...www.tonymacx86.com
About the Thunderbolt issue yes, there are 2 Gigabyte models, at least here in spain. I think both could be patched but this matter I am not the indicated as I have not test myself and I don't know what works and what not.
Can be done, but you need to get dirty if you want that kind of thing
