Running CWWK Q670 LGA 1700 NAS Mainboard with 6x nvme and unRAID OS

Hello,
I am trying to run this motherboard (this cwwk eshop link) with 6x nvme drive, 2 in slots of MB and 4 in the extension board connected with SFF 8643 and power molex connector (from sata from power source).

I am interested in using it with unRAID OS. It seems to run well, but I am getting errors such as these:

I was wondering if somebody knew something about it or if you can provide link for some firmware/bios updates I might be missing. My bios is version from december 2024.

Thank you for any assistance.
