Hiding A Specific-Indexed Element In An ItemsControl's ItemTemplate - wpf

Question

In my WPF/MVVM app, I've got a ListBox with an ItemTemplate; I'm trying to figure out a way to hide a particular element in the template, only for the 0th item in the list. First, some simplified boilerplate:
<ListBox ItemsSource="{Binding MyItems}" AlternationCount="999999" >
<ListBox.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="{Binding Path=(ItemsControl.AlternationIndex), RelativeSource={RelativeSource AncestorType=ListBoxItem}, StringFormat='{}{0}: '}" />
<TextBlock Grid.Column="1" Text="{Binding Name}" />
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Now let's say I want to hide the "Name" for just the 0th item. As I'd ideally hoped to do this entirely in XAML, I was attempting to leverage an extremely handy extension I often use, CalcBinding, which lets you write calculated binding expressions in XAML (note: it automatically converts between boolean & visibility for you):
<Button Content="Cancel" Command="{Binding CancelCommand}" Visibility="{c:Binding 'ProgressPercent > 0'}"/>
So in this case, I'd thought of something like:
<a:EnumEditBox Visibility="{c:Binding Path='(ItemsControl.AlternationIndex) == 0', RelativeSource={RelativeSource AncestorType=ListBoxItem}}" />
However, this and all other attempts seem to yield errors. In this case, the error is: BindingExpression path error: 'ItemsControl' property not found on 'object' ''ListBoxItem' (Name='')'. BindingExpression:Path=ItemsControl.AlternationIndex; DataItem='ListBoxItem' (Name=''); target element is 'EnumEditBox' (Name=''); target property is 'Visibility' (type 'Visibility')
So my questions are:
Is it possible to do what I'm attempting, solely in XAML?
If not, how might I otherwise accomplish this (to hide an element for the 0-indexed item in a ListBox)?
Any pointers would be greatly appreciated :)

The element in the ItemTemplate could have a Style with a DataTrigger on the AlternationIndex property:
<ListBox.ItemTemplate>
<DataTemplate>
<Grid>
...
<TextBlock Text="{Binding Name}">
<TextBlock.Style>
<Style TargetType="TextBlock">
<Style.Triggers>
<DataTrigger
Binding="{Binding Path=(ItemsControl.AlternationIndex),
RelativeSource={RelativeSource AncestorType=ListBoxItem}}"
Value="0">
<Setter Property="Visibility" Value="Collapsed"/>
</DataTrigger>
</Style.Triggers>
</Style>
</TextBlock.Style>
</TextBlock>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
