I didn't get your question the first time.

By default the up arrow just goes to the previous element.

This is close but not right:

(define-key minibuffer-local-map [(up)] 'previous-matching-history-element)

but it might lead to a solution.

I think you want the up arrow when not on the first position to do a
match.
