Bulk removal of Shared Link folders and files

Is there a way to remove "share a link" from the existing folder and all subfolders in the hierarchy? My org has shared many folders by link without realizing that these folders and subfolders are viewable by anyone with an account on our WorkDocs. This is a big security issue and would like to resolve it by turning off all the link-shared files and folders without having to go in every single folder to hunt down shared links.
