using Canvas example above I built a customization model and view so you can control the values via a model and edit them in code, bools aren't always a yes/no/(n/a) so Here's how it looks in MVC5.

using a generic model for the nullable bool

public class Customisable_NullableRadioBool
    {
        public bool? Result { get; set; }
        public string TrueLabel { get; set; }
        public string FalseLabel { get; set; }
        public string NullLabel { get; set; }
        public string AttributeTitle { get; set; }
    }

Here's the CSHTML to be stored in: ~/Views/Shared/EditorTemplates/Customisable_NullableRadioBool.cshtml

@model Customisable_NullableRadioBool
@Model.AttributeTitle


    
        @Html.RadioButtonFor(x => x.Result, "", !Model.Result.HasValue ? new { @checked = true } : null)
        @Model.NullLabel
    
    

    
        @Html.RadioButtonFor(x => x.Result, true, Model.Result.GetValueOrDefault() ? new { @checked = true } : null)
        @Model.TrueLabel
    
    

    
        @Html.RadioButtonFor(x => x.Result, false, Model.Result.HasValue && !Model.Result.Value ? new { @checked = true } : null)
        @Model.FalseLabel
    

And then you can reference the generic class and the editor template through the rest of your project and render the editor template like this.

@Html.EditorFor(m => m.YourCustomisable_NullableBool, "Customisable_NullableRadioBool")

And the rendered output examples
