How to extend the base controller in Yii2?

Question

opencart

Good day to all!
Tell me how to make all controllers inherit not from the base one, but from the custom one, which in turn is inherited from the base one. In particular, you are interested in where to write the path and what to write in the controller itself? And how to use the same controller in the module?
Thanks in advance.
