GTmetrix & Leverage browser caching

Does anyone have any experience with passing GTMetrix score for " Leverage browser caching"? My site scores great across all other categories except for this one, due to external scripts on the header such as Google, Facebook, etc.

The typical response is to update your .htaccess file with these cache settings, but that is not an option on Pantheon. It is also not recommended to edit nginx config, so not sure wha t to do here.
