How do I Reduce my high bid

[neiuk-bryxtr2]

I'm the highest bidder on an item but don't want it anymore. Hopefully I will be out bid but I still have quite a substantial amount remaining from my current to high bid amount.
How do I remove my auto high bid amount?

Change of Mind is not an acceptable reason for retracting a bid.
