Bazzite would be my suggestion. Throw the full install on the ssd then format the HDD for general storage. I’d be a little concerned about the 1060 3GB GPU though. Drivers will likely be fine, but the “10 series” have notoriously awful async compute and take a much larger penalty when running games/apps under proton/vulkan if I recall correctly.
The bazzite project website has an explicit “how-to” for extra drives. Worked for me with no issues, though I am definitely more experienced with tinkering with that kind of thing.
