https://clang.llvm.org/docs/ClangFormat.html#git-integration tells you how to narrow it down to just your changes. Once that's setup you can use the command from the comment the bot left.

Sometimes it will try to format too much, in which case it's fine to ignore it, but looking at what the bot reported here that's not the case.
