Remove NavigationView gap in Content area (WinUI 3 version)

Question

Anyone know how to reduce or remove this padding on the content area of NavigationView (WinUI 3)?? I'd like to do this without using a Style. Is there a resource I can override?

The reason I ask is because if you remove the Back button, the area is not correctly aligned when in narrow view.

Based on the solution provided by @Andrew-KeepCoding, the only change needed to achieve this was the name of the Key:

<NavigationView Header="Sample Page" ...>
    <NavigationView.Resources>
        <Thickness x:Key="NavigationViewMinimalHeaderMargin">24,0,0,0</Thickness>
    </NavigationView.Resources>
</NavigationView>
