I have been told I can't combine upstream of the inverter.

Ideally, you would keep each string separate to benefit from the dual trackers – this would mean four DC disconnects if you went with a standard product like a Square D HU361RB. If you combine each of the two strings out at the array(s) then you could get away with two disconnects, one for each inverter. Neither option is ideal.
