May Node-Red communicate with third-party CAN?

Hi, you'll probably guess from the following that this is not an expert question. Anyways, I'll give it a try:

Is there any way to let Node-Red on Venus or Cerbo communicate with an external device via a proprietary / third-party CAN protocol (based on CANopen)? I imagine to build outgoing or decompose incoming messages with e.g. a function node and/or an appropriate -contrib-.

What is the best way to do the hardware-interfacing between the Venus/Cerbo and the external device?

What is the best way to implement a CAN-communication in Node-Red on Venus/Cerbo?

Would be nice to use the power of Venus/Cerbo with Node-Red for extended control tasks. Therefore this question as part of a general feasibility check.

Thx,
Thomas
