I don't see such list anywhere but I know the current models supporting bifurcation are the 5820, 7820 and 7920.
I'm looking to upgrade from my XPS 8930 to a model (consumer or workstation) that supports my increasing storage needs with multiple Nmve M.2 storage 2280 form factor -- either at least M.2 slots, or using bifurcation via PCiE slot.  I'd prefer to stick with Intel, such as an i9.  I'm thinking there should be a list somewhere...
Current Dell models supporting bifurcation?
