Hi - this library is a very thin wrapper around the can2040 project, which doesn't have this functionality. (https://github.com/KevinOConnor/can2040). Your program will have to receive all CAN frames and discard those you don't need.

From: https://github.com/KevinOConnor/can2040/blob/9e761ae353ea473e24c8bba226e10afad8a919ff/docs/API.md?plain=1#L143

The can2040 code does not implement receive message filtering.

It is expected that the caller will implement any desired filtering in their callback function.
