We stay at YC CL frequently but we aren’t drinkers, so have never asked. But all reports on the Y & B and club level threads are that yes, you can ask at any time & they will get what you want for you.
For any readers, any and all CL will provide a guest (of proper age) adult beverages during operating hours, upon request. It doesn't have to be out. Just have to ask. No one judges if you want wine or beer with breakfast
