Problem installing Ubuntu 20.04 on Dell Inspiron 16 Plus 7630

Hi,

I have recently bougth a Dell Inspiron 16 Plus (7630).

-Processor: 13th Gen Intel(R) Core(TM) i7-13620H
-SSD: NVMe PM9B1 NVMe Samsung 1024GB

I work with RoS Noetic and so I should install ubuntu 20.04 in dual boot with Windows 11, but when I run the installer I am not able to find my SSD, moreover the "wifi step" in the installer is missing. I have already tried to turn off BitLocker, Fast boot and SecureBoot, I use also the ubuntu option "nvme_load=YES ", but it is still not working.

There is no ACHI option in the BIOS.

can somebody help me?

Thanks a lot
