OCIP Job - Zero Amount General Liability Payroll Fringe

Looking to see how to set up OCIP job to calculate general liability payroll fringe to zero. I found instructions on how to set up OCIP to calculate workers' comp (WC) to zero but one of our new jobs is an OCIP job (just GL, not WC).

Right now, our GL fringe's calculation method is set to 'Total pay' (percent).

Could/should a formula be used instead?
