You can use metadata,

[Fact]
public void MetadataBindingExample()
{
    string metaDataKey = "key";
    kernel.Bind().To().WithMetadata(metaDataKey, true);
    kernel.Bind().To().WithMetadata(metaDataKey, false);
    kernel.Bind().To();

    var weapon = kernel.Get(metadata => metadata.Has(metaDataKey) && metadata.Get(metaDataKey));
    Assert.IsType( weapon );

    weapon = kernel.Get(metadata => metadata.Has(metaDataKey) && !metadata.Get(metaDataKey));
    Assert.IsType(weapon);

    weapon = kernel.Get(metadata => !metadata.Has(metaDataKey));
    Assert.IsType(weapon);
}
