I see, no problem
I don't think anyone has managed to get Thunderbolt to show up correctly in System Prefs. I played around with injecting all the device properties from a Macbookpro13,2 and it didn't have any effect. The best I can get is to have Thunderbolt show up under PCI. I'm messing around with a Z270X motherboard which has the same TB chipset as the latest MacBook Pro's (the X99's use an older chipset from 2015) so we'll see if that is any different. Right now I'm just stoked that my USB 3.1 ports (Type-A and Type-C) both work at 10Gb speed and sleep/wake correctly via the ssdt I posted. I did tweak it a little bit more with correct device properties, so it's attached here.
