Jetbot without Pioled display

Is it possible to build the Nvidia Jetbot (github.com/NVIDIA-AI-IOT/jetbot/) without the Pioled display? For example, connecting the jumper wires directly from the Motor driver to the Jetson Nano’s 3.3V, SDA, SCL, GND pins.

Also, is there a minimum power supply that the motor driver needs?
