Hi,
In a product listing menu/module you can select the sorting column (and the sorting order).
That value is fixed which means that the user can't change the sorting value or the sorting order in the front-end ; and that what the filters are providing (with also the search and other kind of filters).

By the way, do not send me private message, use the "contact us" form instead.
