Using two different Nvidia GPUs for machine learning?

Is anyone here using two different Nvidia GPUs for their machine learning projects? If so, how does that work?

I've got an RTX 3090 and an RTX 2070 Super, and I'm trying to figure out if it's possible to use them both on the same rig for machine learning purposes (i.e. loading each one with a different model or splitting batches between the two).
