MultiGPU Path trace rendering with RTX 4090

I’ve been looking around for a way to use 2 RTX 4090’s to a Path Tracer render from the sequencer.

It seems like since Nvidia abandon NVlink and SLI on the 4090 there is no way to use 2 cards to render a scene faster and that the nDisplay/multi-process rendering workflow is for using multiple GPU’s to render to multiple displays and NOT for use in rendering Path Tracer/offline content.

Am I understanding that right?

Many Thanks!
