The underlying due_can library has support for enabling listen only mode. This mode essentially disconnects the TX line so that one is unable to have any effect at all on the connected bus - no ACK, no frame sending. In some cases this mode might be preferable for safety as it doesn't allow for any "oops" moments where you break the bus and cause things to fault.
Listen Only mode was implemented for the two differential CAN buses a LONG time ago. I just forgot to update this issue. However, it is still not implemented properly for the new single wire CAN interface
