So I would say not configured and not supported are equivalent. In our case if there is nothing useful for the EC to do with a specific threshold (e.g. warn), then we don't set it. I think chromebooks send a notification to a userspace daemon on warn threshold, but we don't have that, so we don't do anything and don't set a threshold.
