ZWave device pass through to docker

I have just started running homeassistant using docker. I used the installer from and now I want to pass a parameter --device to the homeassistant container. From what I understand this is started by the supervisor so where are the settings used to do docker run?

You installed hassio, you don’t manage the container like a normal docker container. Your devices are already passed through. Just use the hardware button and look for the device name.

Thank you!
