M.2 PCIe NVMe X1 Adapter with Aluminum Heat Sink, Support PCIe 3.0 4.0 X1 X4 X8 X16 Slot.

There isn't a native slot. You could get a x1 adapter to put underneath your GPU, but it'll cut down the speed a bit. Still would be faster than a SATA SSD. https://a.co/d/00DSbZsn Id recommend saving for an entire upgrade though.
