What is in manual mode? Do you mean the device connected to automatically goes into manual when disconnected? If so then I assume you can put it into manual mode by sending it the appropriate data.  
If you mean that control is being done by node red rather than the device, there is no need to disconnect, just don't send it any data, and ignore anything it sends
