FontImageSource - Color greyed out if ToolBarItem disabled

is possible to grey-out a FontImageSource - Icon if the parent ToolbarItem is disabled?

<ContentPage.ToolbarItems>
    <ToolbarItem
        Command="{Binding StartContainerCommand}"
        CommandParameter="{Binding Container}"
        IsEnabled="{Binding Container.State, Converter={StaticResource IsEqualConverter}, ConverterParameter=exited}"
        Text="Start">
        <ToolbarItem.IconImageSource>
            <FontImageSource FontFamily="faLight"
                    Glyph="&#xf04b;"/>
        </ToolbarItem.IconImageSource>
    </ToolbarItem>
</ContentPage.ToolbarItems>

In the case above the Text of the ToolBarItem is grey but the Icon stays black or white. If possible I would like to do it with styles so I can the same behaviour for all my ToolBarItems.

I ended up using the following solution:

I created a converter that translates a boolean value to a colour:

public class EnabledColorConverter : IValueConverter
    {
        public object? Convert(object? value, Type targetType, object? parameter, CultureInfo culture)
        {
            if (value is bool isEnabled && Application.Current?.Resources != null)
            {
                if (isEnabled)
                {
                    return Application.Current.RequestedTheme == AppTheme.Dark
                        ? Application.Current.Resources["TextDark"]
                        : Application.Current.Resources["TextLight"];
                }
                else
                {
                    return Application.Current.RequestedTheme == AppTheme.Dark
                        ? Application.Current.Resources["TextDisabledDark"]
                        : Application.Current.Resources["TextDisabledLight"];
                }
            }

            return Colors.Gray; // Fallback color
        }

        public object? ConvertBack(object? value, Type targetType, object? parameter, CultureInfo culture)
        {
            throw new NotImplementedException();
        }
    }

And used it like that in Xaml:

<ToolbarItem
    Command="{Binding StartContainerCommand}"
    CommandParameter="{Binding Container}"
    IsEnabled="{Binding Container.State, Converter={StaticResource IsEqualConverter}, ConverterParameter=exited}"
    Text="Start">
    <ToolbarItem.IconImageSource>
        <FontImageSource FontFamily="faLight"
                         Color="{Binding Path=IsEnabled, Source={RelativeSource AncestorType={x:Type ToolbarItem}}, Converter={StaticResource EnabledColorConverter}}"
                         Glyph="&#xf04b;"/>
    </ToolbarItem.IconImageSource>
</ToolbarItem>
