Yes, if you'd like to hide someone from your Instagram stories, but not all of the other posts on your Instagram account there is a way to do this!
How Can I Hide Someone From My Instagram Story?
If you don't want someone to see your story, you can hide your story from them and prevent them from seeing anything you post to your story in the future. To hide your story from someone:
Keep in mind that hiding your story from someone is different than blocking them, and doesn't prevent them from seeing your profile and posts.
Your account's privacy setting also affects who can see your story. If your account is set to private, only your approved followers can see your story. If your account is set to public, your followers can see your story from Feed and anyone can see it from your profile.
