Can you train a cat to meow less?

I’m temporarily looking after a cat. He’s a funny little thing and I quite enjoy having him around, but he’s doing my head in with his attention-seeking meowing! He’s got food, he’s got his litter box, he’s not looking to go out (indoor cat) and he doesn’t particularly appreciate when I pick him up.
He just keeps crying for attention and expects me to follow him around….....any suggestions on how I can make him more content and give me a bit of peace and quiet in the morning?
