To make a long story short, you can't.  The Apple 5.25-inch disk interface
card supports at most two drives.  Since a Duodisk is, of course, two
drives, you're already maxed out.

If you want more than two drives, you'll have to get a second interface
card and plug it into an unoccupied slot.  If you want more than four
drives, you'll have to get a third interface card, and so on.

I have three 5.25-inch disk drives on my Apple IIGS.  This requires two
interfaces:  one drive is connected to the internal disk drive interface
(along with my 3.5-inch drive), and the other two are connected to an old
Disk ][ interface card in slot 5.  (Normally I keep the slot 5 drives
switched out, but for a few older programs three drives makes life a lot
easier.)
