How to hide manager questionnaire responses before review meeting?

Content (required):

We accidentally started performance with the wrong setup but I'm hoping someone has a better bandaid than what I have right now. I built the Process Flow with a Review Meeting and I'm learning now that it should have been with Manager Release instead. The manager questionnaire visibility was set to yes but we found that makes the answers visible before the review meeting has taken place which is not our desired behavior. Is there an EL expression I can use on that section so the employee cant see it until the review meeting has taken place
