SAGE Pro X299 II and ThunderboltEX 3 card

Hello,

I tried installing the ThunderboltEX 3 in my ASUS Pro SAGE X299 II MOBO but doesn’t work. I have enabled the TB function from BIOS and it only offers two options 1. Disable thunderbolt or 2. PCI-E lane 2 BUT my PCI-E lane 2 is completely covered by the Gigantic ASUS RTX 3090 GC … what should I do? Is it possible to run TB from a different lane? how? I could not find the option in the Bios.

Many TIA,
Giovanni*
