There are GPU-accelerated database engines which can stream the database database from NVMe. I am not sure if they do direct device-to-device transfer which has only become supported recently or whether they still need to bounce through the main memory. In raytracing complex scenes can exceed your VRAM so if you don't want to fall back to CPU tracing you need a renderer that can swap parts of the BVH in and out on demand.
