It is possible to use two H-Bridges like those on the DRV8835 Dual Motor Driver Kit for Raspberry Pi to control a single bipolar stepper motor like the ones you mentioned. If you want to use your DRV8835 board, you can look at this post on our forum for more information about how to connect the two coils and how to control the H-bridges. You also might be able to find other tutorials on the web that provide more explanation about how to use a pair of H-bridges with a bipolar stepper motor.
The maximum coil currents for the two motors you listed are below the maximum continuous rating for our DRV8835 board (1.2A), so it should be capable of driving either of those two motors. You should be aware that the NEMA 17 motor you mentioned requires a 12V supply to reach that current and the maximum supply voltage of the DRV8835 is 11V, so you would need to use a lower voltage supply and the coil current (and therefore, the motor torque) would be lower than the specified maximum. The 12V and 24V ratings for the other motor you listed seem to be supply voltages when used with a current limiting stepper driver like the A4988 I mentioned in my last post. To use the DRV8835, you would need to determine the voltage at which the motor’s coils will draw their rated current and use a supply voltage that does not exceed that.
