Thanks for this guide.
I can get it work on my HP EliteBook 850 G5. I have thunderbolt in legacy mode in BIOS and I can connect USB-C drive.
However it breaks sleep mode. When I tried to wake from sleep I needed to shut down and start again with this error:

panic(cpu 2 caller 0xffffff7f9e352399): "NHI0(MacBookPro15,4): thunderbolt power on failed 0xffffffff\n"@/AppleInternal/BuildRoot/Library/Caches/com.apple.xbs/Sources/IOPCIFamily/IOPCIFamily-370.100.21/IOPCIBridge.cpp:1398

Nevermind, I just get it to work!
Thank you so much for this solution. I can finaly switch TB3 in BIOS to "Native + Low Power mode".
All works including sleep.

BTW. I just tested that SSDT files are enough. I don't need kext and driver to work.
