I believe the issue is that the library recognizes it's on the ESP32 architecture and defaults to the inbuilt CAN controller. How can I force the MCP to be the one used?

That MCP2515 is a module that comes with a TJA1050 controller, right? The CAN controller works at 5V logic levels, not 3.3V.
Get a genuine SN65HVD230 module (there are many with fake chips out there). It'll work well with this library if you're using the old ESP32.
You can also try using the native TWAI driver.
