I am having a hard time discovering the location for pin outs that support the CAN 2.0 interface on the ESP32. Can you please direct me to the appropriate documentation?

The ESP32 has an internal pin mux that allows you to route a fair few signals, including the CAN bus, to any appropriate pin. In this case, any GPIO that isn't used otherwise (e.g. for connecting the main flash) and can be both input and output (so GPIO33 and below) can be used.
