Skip tests during the CI/CD pipeline depending on changes

I've got an idea, which I want to validate with you.

We have a multi module project. During the PR build, we always execute tests, even if the changes from the PR do not affect any modules.文章源自玩技e族-https://www.playezu.com/179282.html

Simple example:
We have a readme file inside our repository. If I want to change that readme file, I have to trigger all the checks and tests, to merge it into the integration branch.
From my perspective it is not a good approach.文章源自玩技e族-https://www.playezu.com/179282.html

I want to change the pipeline in that way, that it checks the changes first. Based on the changes, it chooses if tests should be executed or not and possibly which tests.文章源自玩技e族-https://www.playezu.com/179282.html

What do you think about such approach? Are there any tools, which can support me here?文章源自玩技e族-https://www.playezu.com/179282.html
