Stop UF service to delete and reinstall app via Deployment Server

I have an issue deploying the Splunk Stream App. The Stream apps are already installed on UF's but I get an error when reloading deploy server and the config can't overwrite as there is a file (NPF) running which stops the config change. I don't have access to these servers so need to try and resolve this issue using either the deployment server or by creating an app with a scripted input but have no idea how to accomplish this. I just need to stop this service, delete and reinstall the stream app if possible. Thanks in advance
