Unfortunately you can’t. If the device doesn’t have a bunch of custom config on it, just factory reset it and generate a new activation code. If it does, take a config backup and then restore portions of it that matter afterward.
Also take a look at the templates you can create in WCH. You can have org- and location-level default configs that automatically apply to everything as well as manual templates to apply config to specific device(s). At the moment, the manually applied templates are the only way to set model-specific values.
