Removing all payment options supporter plugin

Hi i would like to remove all the payment options for the supporter plugin (we are using another form of payment which manual- we extend the blogs our selves). How would i do so. Is there an easier way then hacking supporter-framework, if not which part do i need to hack to remove the payment options. Also if i want to add custom text/html in supporter where there payment option is at the moment where would i do this

cheers
