You won't be done eating by 9:30 unless you're speed eaters if that's what you're asking. Even if you pre-order, you still have to take care of payment, find a table, and wait for food to be delivered.
But a 9:30-10:30 FP+ window should be fine. Both A&E and 7DMT are close by and you should have no problem getting to one before 10:30.
