How to display posts by category on Tag archive page

Is there a way to display the posts that have a particular tag by category when the archive page is displayed?

For example, on the https://www.domain.com/tag/slug/ where it displays all posts tagged with “slug”, can you then have the list of posts displayed so that first it displays all posts tagged with slug which are in category1 and then all posts tagged with slug which are in category2.
