Thinkpad x1 extreme - Un-allowed DMA

On my new Thinkpad X1 Extreme, I can't activate Bitlocker "automatic mode" as it should be with Windows 10 Pro 1809.

I have a fully operational TPM 2.0:



But as shown in system information, it's due to "Un-allowed DMA capable bus/devices(s) detected":



With Vantage, I made a full update of the system, so I belive BIOS and everything is up to date.


Is there a way to correct what Windows thinks is a DMA threat ? Somethink else to update ?


Thank you.
