Can the navigation on the Dashboard of an app be different from other pages?

So, we are having an argument in our company regarding the navigation. On the Dashboard, the user sees a Hamburger menu in the left upper corner and his profile picture, username, notifications icon and a Logout button in the right upper corner and the Dashboard contains cards, each one leading to a specific page.

All good till here, but when the user enters a specific page, the hamburger button disappears and the navigation bar becomes a bar with all the subsections listed on it, plus the Dashboard icon, the user profile pic, name and Logout button. This navigation is present all over the app, but not on the Dashboard.

Should the navigation be specific the same, all over the app?
