Sn850x not found on Ubuntu 22.04


I’m trying to install Ubuntu 22.04 on a machine where I have the SN850x installed.
I have in fact, tried this on two very different machines, but with no luck.
I have installed Windows just fine, so the disk is working. I have also updated the firmware to the latest version, but still, no luck.

Using any kind of partitioner on Linux show no secondary disk (Linux is installed on the first disk)

Any ideas?

Thanks in advance
