Ability to disable drag&drop on specific kanban groups/buckets

I have a use case where we’re using a kanban board to manage the progress of opportunities. I’d like to allow the user to drag&drop their opportunities between stages except for the closed won / closed lost stages, where I’d instead like to force them to use an action button to move the opportunity so that we can open a modal form to ensure they fill in some required information. Alternatively, the ability to trigger an action when a record is dropped into a certain bucket would be great.
