Corebook X exchange ssd m2 sata 256gb to 1TB

I would like to change my laptop’s internal SSD.
Now I have the W8000S M.2 SATA 2280 SSD 256GB
I would like to mount a 1TB m.2 ssd.
Can you tell me a compatible SSD?
I tried with an NVME SSD 1TB ssd but it is not read by the bios.
I thank everyone in advance

You cannot use an MVME drive in the boot drive slot. As you discovered, the bios won’t recognize it. Someone else in the forum indicated that the secondary slot will accept an MVME SSD.
