You can use interactive rebase. The answer from this post gives you an example:
Change commit author at one specific commit.
The author asks for changing author at a specific commit, but interactive rebasing can be used to change authors of multiple commits if you
edit all commits that you wish to change.
Other potential useful techniques related to interactive rebasing could be found in the Pro Git book
