from the name, Im guessing this board has the same step/direction/enable lines from Z going to the two stepper drivers.
Ie its not possible to over ride this behavior in firmware, you have to actually modify the circuit board.
got a multi meter? we can test this
with the printer off and usb unplugged (ie making very sure its off with no power)
check continuity from the step pin on Z1 to the step pin on Z2 if they are connected. your out of luck.
