How to disable page opening at invalid url /valid-cat/trololololo-notvalid/valid-article?

Question

Joomla

Good afternoon. there is a category /valid-cat/ which contains valid-article. The page opens at /valid-cat/valid-article.
But if you add any invalid subcategory to the URL (eg /valid-cat/trololololo-notvalid/valid-article), the valid-article material will still open, but you need to give 404. How to solve this problem?
