How to hid scrollbar in navigationview

You need to create a default style of NavigationView. Then find the NavigationViewList which is named as MenuItemsHost. Set the ScrollViewer.VerticalScrollBarVisibility property of the NavigationViewList to Hidden.

Like this:

            <NavigationViewList x:Name="MenuItemsHost"
                            HorizontalAlignment="Stretch"
                            ItemTemplate="{TemplateBinding MenuItemTemplate}" 
                            ItemContainerStyle="{TemplateBinding MenuItemContainerStyle}"
                            ItemTemplateSelector="{TemplateBinding MenuItemTemplateSelector}"
                            IsItemClickEnabled="True"
                            ItemContainerStyleSelector="{TemplateBinding MenuItemContainerStyleSelector}" 
                            Margin="0,0,0,20" Grid.Row="6" SelectionMode="Single" 
                            ScrollViewer.VerticalScrollBarVisibility="Hidden"
                            SingleSelectionFollowsFocus="{Binding TemplateSettings.SingleSelectionFollowsFocus, RelativeSource={RelativeSource Mode=TemplatedParent}}"
                            SelectedItem="{TemplateBinding SelectedItem}"/>

To create a default style of the NavigationView, please open the Document Outline window in Visual Studio. Then find the NavigationView control, right-click on it, choose Edit Template->Edit a Copy. The Visual Studio will automatically generate a default style of the NavigationView.
