In what way?
Dueling parry isn't a stance, so they don't conflict, and the 2 fears have nothing to do with each other'so requurements. You must be unarmed for dragon stance, and you must have a 1 handed weapon and a free hand for dueling parry.
Using them at the same time is easy, but they aren't doing anything together.
