Quad M.2 on Intel C602J

I’ve tested it by now, it works - with modded bios. It’s maybe interesting since these server a now <1000€ and 15core Cpus 20€

I have the same Mobo (x10qbi).
Could you give me a hint how I could get such a card with NVMe running on it? The system is running TrueNAS. It still have the stock bios from supermicro 3.2a.
