I haven't looked in detailled but most probably disabling reporting for subscriptions is not implemented, so you need to go through the subscription code and add support for it. Probably not very complicated but you need to know well python and read(and understand) the OPC UA spec

Sorry I don't have time to look at implementing this. The best way to get help is to try yourself and make a "work in progress" pull request so we can review it.
