How to change last name on facebook page?

...without having it posted for all to see.
I saw where you can change your name twice with the second one being a permanent thing.
Is there a setting where the last name can be changed and not be posted?
Okay...I don't want my actions to be noticed on my page. I just want to change my last name without anyone seeing what I just did. Is there a setting for privacy, etc I can use when I make that action?
