When having a clickable textblock in a listview, there is a blue highlight around the text block that appears before hovering over the actual text. How would I remove the highlight (or glow if that is the proper term)?

<Grid x:Name="menuGrid">
    <ListView Template="{DynamicResource MenuListViewTemplate}" ItemsSource="{Binding MenuHeaders}" Name="Menu" SelectionChanged="Menu_SelectionChanged">
        <ListView.Style>
            <Style TargetType="{x:Type ListView}">
                <Setter Property="Background" Value="Navy"/>
                <Setter Property="BorderBrush" Value="Navy"/>
            </Style>
        </ListView.Style>
        <ListView.ItemsPanel>
            <ItemsPanelTemplate>
                <StackPanel Orientation="Horizontal"/>
            </ItemsPanelTemplate>
        </ListView.ItemsPanel>
        <ListView.ItemTemplate>
            <DataTemplate>
                <TextBlock Text="{Binding HeaderName}">
                    <TextBlock.Style>
                        <Style TargetType="{x:Type TextBlock}">
                            <Setter Property="Foreground" Value="White"/>
                            <Style.Triggers>
                                <Trigger Property="IsMouseOver" Value="True">
                                    <Setter Property="OverridesDefaultStyle" Value="True"/>
                                    <Setter Property="TextDecorations" Value="Underline"/>
                                    <Setter Property="FontWeight" Value="Bold"/>
                                </Trigger>
                            </Style.Triggers>
                        </Style>
                    </TextBlock.Style>
                </TextBlock>
            </DataTemplate>
        </ListView.ItemTemplate>
        <ie:Interaction.Triggers>
            <ie:EventTrigger EventName="SelectionChanged">
                <ie:InvokeCommandAction Command="{x:Static event:GlobalCommands.SelectedCommand}"
                                        CommandParameter="{Binding ElementName=Menu, Path=SelectedItem}"/>
            </ie:EventTrigger>
        </ie:Interaction.Triggers>
    </ListView>
</Grid>

What I have tried:

I've tried in a few different places to make the highlight transparent or turn it off to the best of my knowledge.
