Hyper M.2 X16 expansion card

Intel I7 9700k
Msi Z390 A motherboard
32GB Ram
RTX 2080 GPU

Friend of mines is trying to find out how to enable the Hyper M.2 X16 expansion card through the BIOS to recognize all four NvMe ssd's installed within the expansion card.

I know it's somewhere in the Bios advanced settings but I'm not very familiar with MSI Bios platform I don't know how to guide him through it if anyone here can help us that would be so greatly appreciated.

The Expansion card is placed on the second PCIe Express port furthest from the CPU

If anyone can provide us with easy to follow step by step instructions on where to enable the card and properly configure it within the MSI Bios we would greatly appreciated.

The motherboard must support PCIe bifurcation. I don't see anything to indicate the MSI Z390-A motherboard supports PCIe bifurcation.

Here's an interesting website:

Note this:

2. For Z390 and Z370 series motherboard, install IRST version 16 or above to use RAID on CPU function. Only Intel SSDs can active Intel RAID on CPU function in Intel platform.

But with MSI Z390 you might get 1 or if your lucky 2 nvme devices to show.
