ASUS ROG STRIX X670E-I GAMING WIFI Thunderbolt didn´t work PCI Tunneling is off

Level 7

I try to run a M.2 SSD Thunderbolt Case at my ASUS ROG STRIX X670E-I GAMING WIFI but it didn´t work.
Thunderbolt Control App says that i need to enable PCI-Tunneling, I looked in Advanced Settings, used the Search in BIOS, but i can´t find this settings in BIOS / UEFI.
All Drivers are up to Date, same as BIOS.

Ok, i get that thing working. There are 2 Ways...1rst  was enabling IOMMU and disabling USB Security, the 2nd Way was reset the BIOS / UEFI when the M.2 Thunderbolt device was connectet.
