I haven't found any agreement on fill light control. Does onvif not support this protocol? |

I am not sure what protocol you are refering to. For control of external add-ons or auxiliary extensions (Washer/Wiper/Lights), the ONVIF devices often use the Auxiliary commands available on the Device Managment Service and the PTZ Service. You can have a look at the SendAuxiliaryCommand method. |

I have seen this method. The description states that users can customize it. Is there a method to query the supported auxiliary commands? |

The available commands can be received from the Device Managment service using the GetCapabilities or GetServiceCapabilities methods. From the PTZ service they can be retrieved using the GetNode and GetNodes methods. |
