No, because the relay outputs are only outputs, and Arduino inputs are inputs, and that would only get data from the cRIO to the Arduino. The question is about sending data in the other direction.
The simplest way is to use as many DIO inputs on the Digital Sidecar as you need to communicate the necessary data. Sometimes that might be a single bit, giving the answer to the question "Am I facing a hot goal right now?"
