This has come up a couple of times lately. Easiest way is to turn them in to virtual pages via RSS (Instagram shut the API off so you cant go that way anymore.)
You can use a service like this one to turn the instagram page into a RSS feed… https://rss.app/rss-feed/create-instagram-rss-feed
You can turn the feed into virtual pages https://getkirby.com/docs/guide/virtual-pages/content-from-rss-feed
The guide on mixing virtual and real content might be useful too, as this lets you add fields to virtual pages (like a toggle to turn the articles on or off)
