The correct answer to this open question is the following.
No, you cannot refrain from addressing the nation. If you are the President, you are obligated by the Constitution to give your state of the union address every year.
Indeed, the Constitution states that "from time to time, the President has to inform Congress about the state of the Union." You can find this information in Article II, section 3, clause 1. Today, this event is known as the State of the Union Address.
