I'll assume you are still applying for a visitor visa, so the waiver you need is a nonimmigrant waiver. When you get denied your visa, and you are denied only for bans and not for immigrant intent, the officer can recommend you for a waiver. If they recommend you for a waiver, they will let you know about the process. If they don't recommend you for a nonimmigrant waiver, there isn't much you can do.
