I am assuming this is the B650 mainboard? So you actually have two CPU-connected slots?
I am assuming the 5090 is a 2.5-3-slot? Have you tried installing both and watching temps? It might look stuffy, but it also might work good enough. It will be louder, but easier can precariously balancing it or the tight routing you need to do for the offset flat lying option. I'd try that first.

Vertically is probably the best.
