【解决方案1】：

您可以通过在 App.xaml 或放置 NavigationView 控件的页面中添加以下代码来简单地覆盖默认颜色资源。

在 App.xaml 中

 <Application.Resources>
    <SolidColorBrush x:Key="NavigationViewSelectionIndicatorForeground" Color="Transparent" />
</Application.Resources>

OR在存在 NavigationView 控件的页面中

 <Page.Resources>
    <SolidColorBrush x:Key="NavigationViewSelectionIndicatorForeground" Color="Transparent" />
</Page.Resources>

根据您的要求，可以modifyNavigationViewItem样式，将SelectionIndicator矩形的宽度设置为0。也可以直接使用下面的样式。

<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">
        <Setter.Value>
            <ControlTemplate TargetType="NavigationViewItem">
                <Grid x:Name="LayoutRoot" Background="{TemplateBinding Background}" Height="40" Control.IsTemplateFocusTarget="True">
                    <VisualStateManager.VisualStateGroups>
                        <VisualStateGroup x:Name="PointerStates">
                            <VisualState x:Name="Normal"/>
                            <VisualState x:Name="PointerOver">
                                <VisualState.Setters>
                                    <Setter Target="LayoutRoot.(RevealBrush.State)" Value="PointerOver"/>
                                    <Setter Target="LayoutRoot.Background" Value="{ThemeResource NavigationViewItemBackgroundPointerOver}"/>
                                    <Setter Target="RevealBorder.BorderBrush" Value="{ThemeResource NavigationViewItemBorderBrushPointerOver}"/>
