VR Works SLI Unreal 4 plugin, will it work on a pair of 4090s without NVLink?

Hi there, I’m interested to know if the NVAPI for VR Works will function without traditional SLI or NVLinked GPUs for 1 GPU / eye stereo VR.

Has anyone tested this recently and would it even work with a pair of RTX 4090s? Or does it need actual connected GPUs. It seems like it shouldn’t but I wanted to make sure.
