Gigabyte X399 Aorus 2990WX and Linux NVME raid

Hi
I have Gigabyte X399 Aorus Extreme with 2990wx and 2 NVME samsung 970 running in Raid 0, setup in bios, with AMD RAIDXpert2. Bifurcation settings set a 16x slot to 4x4x4x4, Setup is correct and it runs fine Windows 10 full speed.

But i cannot see the raid in Linux, i tried Ubuntu 18.04.1 LTS and Mint. They don`t show my raid. I cannot find AMD linux raid expert drivers/software anywhere( googled too).

NVME drives are in Asus Hyper m2 card. Do i need to somehow install the card first in Linux maybe?

I would like to acces the raid from both Win and Linux, based on what i boot into. It works when the drives are on NVME raid controller as NON raid drives(setup in bios), but not when set as RAID 0 drives.

thank you

Hello, has not anyone allready experience with that setup on linux? I am interested in that too. Thanks for your support.

add: Hey, if found here a tutorial - had not jet time to test it. Maybe it helps someone:
