That card DOES NOT configure in a RAID, in fact it has no controller at all. The motherboard must support PCIe bifurcation and further, at least for consumer boards, you can't easily run a discrete GPU with such a setup. There are adapters with controllers that will work without PCIe bifurcation (but generally the GPU condition remains) that CAN do RAID but you do not HAVE to do RAID on them. There are further adapters with controllers that MUST do RAID, for example Gigabyte's x8 PCIe 3.0 with the Marvell controller, because they don't bifurcate lanes.
I have an extensive write-up of the Hyper
