I'm referring to the tiny boxes that started appearing in the "All day events" area about a month ago.

This is a new visual display in iOS 18 and Sequoia for all day events. There is no option to remove it.

Could you please clarify what specific calendar icons you're referring to? Are you going to uninstall Calendar to remove the icon, or you are just referring to the event icons?
