This happens to my mom and her cats, because she feeds them wet food in the morning. I did some reading and found that feeding them in the morning will make them want to wake you up for food in the morning.
When I got kittens, I made it a point to only feed them wet food when I came home from work and never in the morning. I found this to work very well as they let me sleep (well, kind of) without waking me up wanting to eat. They know if they are hungry, there is dry food and to feed themselves.
My cats still wake me up through the night, but this is mostly due to the fact they want to play fetch at 3 am or they were on the prowl and making noise. By playing fetch, I mean literally playing fetch. My female will usually drop her favorite toy on me or next to me and lick my arm until I grab her toy and throw it out the bedroom door which she will go and retrieve and repeat the process should I have fallen asleep before she came back, which I'm glad of.
So the only thing I have for you to try would be changing up when they get wet food, but if ignoring them doesn't work, it may be too late to try to change up their feeding time.
I am also gone 10+ hours a day, so I understand your hardships of not being able to play with them. Usually when I get home, I spend the next 3 hours playing with my cats, sometimes by choice, other times it's because they yell at me.
