How to run a code formatter on a feature branch only, changed files only ?

Hello,
how to run a code formatter (black) on a feature branch only, changed files only, with filter-repo or lint-history?
In order to prepare for a rebase onto master which got a commit re-formatting all .py files.
Some 50 commits (only).
Or is filter-branch still better for that?
