Can you sleep train and still have a long breastfeeding relationship?

I’m on the fence about sleep training my almost 6 month old. I sleep trained my first and he’s been an amazing sleeper ever sinceR this age so I’m not against it but I pumped and bottle fed him. This baby boy is exclusively breastfeeding and hates bottles and pacifiers. He fills diapers at night which makes me think he’s not ready to sleep through the night. I’m also concerned about my supply once he stops feeding at night. He wakes up anywhere from 3-10 times at night. I would love to sleep more haha! I have a toddler to care for so I really would love more sleep.

My question is, should I just keep co-sleeping and maybe he will stop needing to nurse on his own? Or should I sleep train? And do you just abruptly stop nursing at night if they wake up once you sleep train? If I Ferber do I just Ferber every time they wake how do you know when they really just need to eat?
