How to wean dream feed

Hello mamas! How do I know if my baby is ready to wean her dream feed? She sleeps at 7-730pm, takes her last feed at 11pm (while asleep) and sleeps till 7-730am. I want to see if i can drop her 11pm feed. She seems to know that she’s getting the 11pm feed cause sometimes when i walk into the room she automatically raises her head and opens her eyes. But goes to sleep while drinking milk. How do i wean? Do you guys cold turkey or slowly drop the amount until 0ml?
