A dispute is when two sides explicitly argue opposite rulings about a particular law. It is not a “dispute” when, like by the oaths, numerous poskim bring something as halacha and some happen to not mention it. That’s called an academic question as to why the others did not mention it.

this ‘academic question’ has been asked by one of the major poskim the avnei nezer and USED in his maskana that they are not lehalacha ….
so that definitely is a dispute ….
