Is it possible to disable PrincipalPermission check for WCF-services in web.config

Question

My wcf-services uses Principalpermissions for authenticating users like follows:

<PrincipalPermission(SecurityAction.Demand, Role:="WCFUser")>

Is there any possibility without changing source code to disable this PrincipalPermission check, like a section in web.config or something similar
