Whether or not that would be advisable is a different question.

Thanks in advance for your patience

I don't know why this would even matter.

The PDB will only supply 40A (at 12 volts) to a motor, or the individual breaker will reset.

That means that only 480 electrical watts can run through your motor anyways.

Stepping up the voltage to 18V drops your maximum amperage to just 26.6 amps.

I haven't looked at the specific motor torque/rpm/current curves, but barring inefficiency, they can only operate at the same maximum power
