should you hide the main navigation on the account page ux

I am currently working on designing an account settings page and within the current design, I do not hide the main navigation. Another designer I am working with is suggesting removing the main navigation once the user is on the account settings page and his reason is to not distract the user from the task they are trying to complete once on this page. The main navigation will introduce things like alert icons in the near future but I'm not sure a badge on the primary nav would be that distracting. Any opinions would be greatly appreciated.
