In addition, many airplanes are designed with Frise type ailerons, which
also reduce adverse yaw by creating extra drag on the up-deflected
aileron (to balance the drag on the down-deflected one).

Is this the same as "differential" ailerons, more "up" travel than "down"?

Well, no. As Anno posted, it's something different.

Interestingly, the post to which I replied was specifically talking about
"differential" deflection, and my post specifically said "in addition". I
think maybe the answer to your question could have been had through more
careful reading.
