I'm still not clear on what you're trying to accomplish so...
That said, I've have two NVMe SSD's in my system directly connected to the motherboard - one being the main boot drive (Windows 10), the other being a data drive and both are accessible without issue. You can see my system specs below (system one).
Perhaps your issue is the fact that you are installing two NVMe drives on a single PCI card and installing that card in a PCI slot.
If so, why are you doing that??? Why not use one or two of the three m.2 slots on the board??? Also be aware some PCI cards won't allow an NVMe drive to OS boot off the card.
I think you need to rethink things if the current solution doesn't work or won't work.
Good luck.
