How to set DropDownButton MenuItem.Icon when using a DataTemplate?

[sn4k3]

I have the following code which allow me to create a DropDownButton with my collection, however I can't see a way to set the Icon on MenuItem.

View:

<DropDownButton>
    <DropDownButton.Content>
        <StackPanel Orientation="Horizontal" Spacing="5">
            <CheckBox IsChecked="{Binding AppSettings.NetworkInterfaces.EnableFilterTypes}"/>
            <icon:MaterialIcon Kind="Filter"></icon:MaterialIcon>
            <TextBlock Text="Type"/>
        </StackPanel>
    </DropDownButton.Content>
    <DropDownButton.DataTemplates>
        <DataTemplate DataType="{x:Type models:EnumViewFilter}">
            <CheckBox IsChecked="{Binding Include}"
                      Content="{Binding Description}"
                      HorizontalContentAlignment="Stretch"
                      HorizontalAlignment="Stretch"/>
        </DataTemplate>
    </DropDownButton.DataTemplates>
    <DropDownButton.Flyout>
        <MenuFlyout ItemsSource="{Binding InterfaceTypeFilters}"
                    Placement="Right">
        </MenuFlyout>
    </DropDownButton.Flyout>
</DropDownButton>

How can I set MenuItem.Icon via xaml?
Note: DropDownButton.DataTemplates already encloses my template inside a MenuItem.

I would try either:

1. Use a style selector. See discussion
2. Use a MenuFlyout.ItemContainerTheme. See docs
