KUU Mingar 3 doesnt detect NVMe m.2 ssd

[bighoss]

Hello

Hopefully somebody could help me

I bought a mini Pc - KUU Mingar 3
this mini mpc is similar to GMKTec Nucbox 4 kb

My Problem is that the pc is not detecting the PCIe m.2 ssd
with the sata ssd it is running w/o probs

This bios is really huge and confusing me - so many parameter to modify and i tried several one
however without success

okay - here the fact as far as can analyse it

What should i set in the Bios to use the PCIe m.2 ssd ?

It will be fantastic if somebody could help me - and if i get the information that the pc cant handle PCIe ssd
than i could finish my try and error investigation and except that only sata is running
