Dashboard polling my network

Dashboard is polling my network. It’s a trivial amount of network traffic, but I monitor all outbound transfers from my PC, even to my local LAN, and I get twitchy.

I realise that it is pining for a Droboshare to appear, so it can enable the middle section of the dashboard, but that is unlikely to happen as I’m using my drobo as a local disk - there was no extra space inside my PC.

Is there some way to tell it to “Calm down, dear; there won’t be one along this way for many a month”?

Or maybe: “Look, you played with the network less than a minute ago. Let someone else play with it for a change!”

Or even “If you carry on like that I’ll lock you inside your room in my firewall, and not let you out”.
