Truenas doesnt see drives after BIOS reset and new CPU

Hello, I have a strange problem. I replaced my broken CPU, and during debugging I cleared the CMOS. Now, with the new CPU installed, all disks are visible in the BIOS; however, TrueNAS doesn’t see them. I’m using NVMe drives in PCIe adapters without bifurcation. I’ve been using these disks for a couple of months, and everything was fine. I have a feeling that it’s some setting in the BIOS and I had the same problem when isntalling system first time. I don’t see the drives in the shell with lsblk.
Do you have any idea what BIOS option might be causing this behavior? The system on the SATA SSDs booted correctly.

P.S. I might have mixed up the order of the NVMe drives in the PCIe slots, but I thought that shouldn’t matter.

Please post details of the hardware in use.
At the very least the motherboard and PCIe adapters but ideally just post it all.

I’m using an ASUS X99-WS/IPMI, and I’m leaving this post in case it helps someone in the future. I managed to get it working, but I changed a few options at once, so now I’m not sure which one actually fixed it xd I’ll check tomorrow and update.

My guess is you turned off the onboard raid controller.

I forgot to answer. I’m not sure why, but it looks like MCTP must be enabled, and it’s disabled by default in my BIOS
