What Bryan said!
I fence my ducks out of my annual garden beds, especially when the plants are itty bitty. Even the big ones and ones they don't eat, they will squish down (most of the garlic around my fruit trees ends up squished by them as they dig for bugs in the mulch around the tree).
But, unlike with chickens, it's really easy to keep a duck out. A short 18 inch fence will do it, or even just making a raised bed. If they're really hungry, they might try to circumvent those things, but most of the time they won't bother. And, thankfully, they don't do damage as quickly as a chicken. So you can see them in there and shoo them out and make the fence a little taller, and no real harm is done.
If you're growing potatoes or kale or daikon radishes, you probably won't even need to fence them out. They don't like the taste of them. There was a span of time when I was unintentionally underfeeding my ducks, and they ate the potato plants. But, as long as mine are fed enough (I feed them at the end of the day), they don't eat my potatoes.
