SSD upgrade?

I solved this on a x399 taichi with a pci-e ssd and in this setup with an 8x pci-e SSD , it's faster then the M2 slot for obvious reasons and on benchmark test also and a hamstrung m2 indeed right under a hot graphics card. the only culprit is do not fill the M2 to 90% cause this will destroy a heated m2 sooner

Wow this is one idiotic set up there, Asrock. You install M.2 slot right under 90C of radiating heat (A GPU), and disable user to place that source of heat (A GPU) to second full PCI-e slot. Way to go!!!

To answer your question. Yes, that and any other SSD without heatsink will fit there, easily, however it will be constantly cooked by your graphics card, because you cannot place your GPU second full length pcie slot.

I have the same SSD, which is fitted right under primary PCI-e slot, and when I got my new GPU and fitted it, SSD was reaching 70C under normal load. Don't even want to think of the temps under full load. So I had to use pcie riser to bring my GPU to the side of the case.
If you don't want to risk your new SSD to fail because of heat, consider using pci-e adapter for your M.2 SSD. You put your SSD into adapter and plug that adapter into your PCI-E4 slot. If you can find some, you can even buy pcie interface NVMe SSDs, but they are very rare these day for some reason
