Here no problem between the 6900 XT Reference and Gigabyte Titan Ridge with modified firmware. Big sur 11.4 with SMBIOS IMAC Pro 1.1 (i prefer this based on my hardware), Weg and Adgpmod = Pikera in the boot arg.
What firmware version are using for Titan Ridge? If you could post a screenshot System Information > Thunderbolt that would be great. I may have to reflash mine.
