How do you stop your dog from eating acorns?

For those of you who live in areas, like me, with loads of acorns all along the streets, sidewalks, and grass how do you keep your dog from eating acorns?

My dog will not stop munching on one each time we go out for a walk. No matter how much I try to avoid the areas with the highest concentrations of them she will still sniff out a lone acorn somewhere and be munching on it in a flash. She is so sneaky too. She knows I will try to immediately get it out of her mouth so she puts it way in the back of her mouth and crunches twice and swallows right after…

Added context: Our HOA has rules that every front yard must have a minimum of 2 oak trees. So we have acorns everywhere. Everywhere.
