I would move your daughter to the room with the best sound isolation and sleep with her. So that when she starts crying, I would take her out of the home , i.e to the backyard or another place where her noises won't be heard.
If she starts crying after 6AM, I feel like it could be okay, since your quiet hours are between 9PM to 6AM.
But if she starts crying BEFORE 6AM, this is an issue, and you would possibly need to bring her to the backyard / front porch etc.
