Pollyfill.io security issue | WordPress.org

Does anyone have an easy way to remove all code references to pollyfill in light of the recent security issue, for WordPress sites that are NOT hosted with Cloudflare? My HTML source code has references to many pollyfill elements but I cannot find them in the source files such as functions.php. Is there some code I could add to the global header to disable or replace the unwanted code without breaking the website? Thanks.
