Here are my Thunderbolt experiences with the GC-TITAN-RIDGE-
NVM23-Elias64Fr.bin on the GC-Titan Ridge.
My hardware:
ASUS Prime X299 Deluxe (1) - BIOS: 2002
Gigabyte GC-Titan Ridge - FW: GC-TITAN-RIDGE-NVM23-Elias64Fr.bin
UAD Apollo 8 TB(2) audio interface
UAD 2 Satellite Quad TB(2) DSP System
Apple TB3 to TB2 Adapter
The Titan Ridge in PCI-Slot-4 plugged in from above (PCIEX16_3)
Bridged the TB header (3 and 1 directly on the card)
TB activated in the bios of the mainboard
Without the bridge, with directly connected TB header cable and without the TB activation in the bios, I always got KP at the start!?
Most important step: Perform a hardware reset on Apollo 8! Without this reset the hotplug with the audio interface did not work! Furthermore the computer froze up when switching off the Apollo!
Required software:
GC-TITAN-RIDGE-NVM23-Elias64Fr.bin flashed to the card with a Raspberry according to the instructions "Mini-Guide for Flashing SPI ROM Chips using Raspberry Pi 3B or 4".
I took the SSDT-TBOLT3-RP05-PORT7-GC-TITAN-RIDGE.aml as a basis and adapted it for my board. I also individualized the DROM area according to the instructions "Thunderbolt DROM Micro-Guide for Gigabyte GC-Titan Ridge".
I tested the whole thing under Mojave 10.14.6 and Catalina 10.15.3. My bootloader is OC 0.5.7
The Thunderbolt bus appears correctly in the system report. All connected devices are listed correctly. Connected my MacBook Pro to the Hacki via Thunderbolt cable, could move files in breathtaking speed without problems.
The UAD software and UAD drivers should be up-to-date and the same on all systems. Sometimes the hardware gets a new FW during an update, if different software versions are installed, the hardware wants to do a FW down- or upgrade all the time!
Many thanks to all involved in this topic!

EDIT:
Here now with the NVM33. I can't see any difference to the NVM23, but I didn't want to flash the card back again for the time being.
I even got my Belkin Thunderbolt™ 3 Express HD dock working with it. However,
I always had to disconnect and reconnect the TB cable once after booting the computer, otherwise it was not recognized. Audio, Ethernet, USB and TB will work then. Only the display port I could not activate...
I connected my UAD Apollo to the Belkin Dock via the Apple TB3-TB2 adapter and even that worked! BUT when I switched off the Apollo, the computer froze.
Without the Belkin Dock there are no problems. I can turn the Apollo off, unplug it, turn it on again doesn't bother the computer.
