Exclude plugin / widget from cache

Hello ! I am using Wp Fastest Cache on a website for a client, and it works great except for a section where I have an Instagram feed using Stratum plugin for Elementor. Because of the cache, the feed often becomes blocked (images do not load, only text/tags). Once the cache is cleared it works again, but I can’t continually clear cache. Is there a way to exclude this section from the cache ?

Thank you !!
