No, because the SQL Server instance only application that knows what the DAC port is. Because hiding the instance through the browser (or turning the browser off) will result in the client tools not being able to connect to the SQL Server, the DAC port cannot be fetched. Because the DAC port cannot be fetched, it cannot be connected to.

It's more like a chain reaction. Shutting down the Browser service causes the instance on a non-default port to be non-discoverable and therefore the DAC cannot be used for administrator connections.

Great line of thought, by the way. In fact, that was what prompted me to write up the QotD in the first place.
