Hi Ken,
You should clone related policy firstly, because it is ADC policy and you cannot modify it. After cloning, you can configure new policy with following options:

When new policy saved, you should switch old policy with new one by using Apply To tab of the policies.

Subject: Fullwidth/Halfwidth Unicode Decoding On URL/Parameter
Dear all,
The alert "Fullwidth/Halfwidth Unicode Decoding On URL/Parameter" happens on one of the request parameter rather frequently. Is there a way to diable this checking on that specific parameter?
Thank you.
