Super Orders / Purchase Order question

One of the steps to installing the Super Orders mod, says...

Install "Purchase Order" Payment Module
The PO tracking system and attached reports won't work without this! Go
to Admin > Modules > Payment, you should find "Purchase Order" at the
bottom. It should look familiar when you install and configure it,
since it mimics the "Check/Money Order" module.

Well, I've done that, but what if I don't want "Purchase Order" as one of the payment options when a customer is checking out? Can I turn off "Purchase Order" and not lose any functionality of Super Orders other than something that relates directly to the Purchase Order payment module? If so, I don't mind. I just don't want to set Purchase Order to "False" and mess something up that I shouldn't.

Thanks for your help.
