Umm... no. He knows everything about us, more than we know ourselves. However, we can still make choices.
Have you ever made a conscious decision in your life after weighing the possible decisions? Safely assuming the answer is yes, that would mean you have made a free choice. Now God could easily have known what decision you would make without influencing you to make it, meaning that you made your decision of free will and yet, God still knew the decision beforehand.
