the defendant is required to pay all or a portion of the fine or restitution. The court may deny the request if it has previously considered the defendant's ability to pay and the defendant's request does not allege changed circumstances. If, at a hearing under this subsection, the defendant proves by a preponderance of the evidence that the defendant will be unable through good faith efforts to satisfy the order requiring payment of the fine or restitution, the court shall modify the order so that the defendant can pay the fine or restitution through good faith efforts. The court may reduce the fine ordered, change the payment schedule, or otherwise modify the order. The court may not reduce an order of restitution but may change the payment schedule.
