More precisely: there's only a C implementation of it. But there is a Lisp
binding as well.

Actually, you can, but it will only have an effect if the function is called
via its Lisp binding. Since built-in functions almost always call other
built-in functions via their C binding, advising display-buffer will not
affect its behavior when it's called by pop-to-buffer.
