Atwood requires a minimum of 30 square inches of unrestricted flow. A 3" duct is 7.06 square inches. Using those numbers, 5 fully open, unrestricted ducts would give 35.30 square inches.In theory any additional registers could be closed.

I would recommend checking the CFM at each register with a flow meter, then closing the desired register/s and check for increased flow at the unrestricted registers.
There are two safety features in the furnace. A sail switch, and high tempperature sensor, of which either can shut down the furnace.
Any good HVAC tech should have a flow meter and be able to test and balance the system.
