It looks like you'll have to create a custom /etc/X11/xorg.conf file.

It's not difficult, but since I don't have two cards here (or two 
monitors), I can't experiment.

Some fun ones to get you started with can be found here:

conf-examples-for-using-multiple-cards-multiple-monitors-751939/

It looks like if you can uniquely identify the hardware (the examples 
used BusID), then you can stuff in two cards and two monitors. Use lspci 
to get the BusID of the cards (I think).

See man 5 xorg.conf for the gory details.

. . . hope this helps.
