If you do not want the agent to know you, then the only option you have is to use fake documents to fraudulently setup the company. It can be effective for some cases, less so for others. But in order to find out more you need to join the forum mentor group as it is not allowed to be discussed on the public forum.
Maybe if you could provide more details of why you want to be anonymous from the agent, what trouble you expect, whether you need a bank accounts, who you are trying to stay anonymous from ultimately then perhaps people can suggest solutions that may be a better fit.
