我想从NavigationView菜单项中删除突出显示
我如何才能使它在某些MenuItems上突出显示的东西不会移动到项目？

只需在App.xaml或NavigationView控件放置的页面中添加以下代码，就可以简单地重写默认颜色资源。
在App.xaml中
<Application.Resources>
<SolidColorBrush x:Key="NavigationViewSelectionIndicatorForeground" Color="Transparent" />
</Application.Resources>或在存在NavigationView控件的页面中
<Page.Resources>
<SolidColorBrush x:Key="NavigationViewSelectionIndicatorForeground" Color="Transparent" />
</Page.Resources>Stack Overflow用户

对于您的需求，可以使用modify NavigationViewItem样式，并将SelectionIndicator矩形的宽度设置为0。您还可以直接使用以下样式。
<Style TargetType="NavigationViewItem">
<Setter Property="Foreground" Value="{ThemeResource NavigationViewItemForeground}"/>
<Setter Property="Background" Value="{ThemeResource NavigationViewItemBackground}"/>
<Setter Property="BorderBrush" Value="{ThemeResource NavigationViewItemBorderBrush}"/>
<Setter Property="BorderThickness" Value="{StaticResource NavigationViewItemBorderThickness}"/>
<Setter Property="UseSystemFocusVisuals" Value="True"/>
<Setter Property="HorizontalContentAlignment" Value="Stretch"/>
<Setter Property="Template">
