Conditionally call static abstract interface member

[weifenluo]

I have an interface with static abstract member:

public interface IWithEntityTypeDescriptor<T>
{
    static abstract EntityTypeDescriptor<T> Descriptor { get; }
    EntityTypeDescriptor<T> GetDescriptor();
}

I can conditionally call the instance interface member GetDescriptor():

void TestMethod1<T>(T instance)
{
    if (instance is IWithEntityTypeDescriptor<T> withEntityTypeDescriptor)
    {
        var descriptor = withEntityTypeDescriptor.GetDescriptor();
        ...
    }
}

However the following code does not compile:

static void TestMethod2<T>()
{
    if (T is IWithEntityTypeDescriptor)
    {
        var descriptor = T.Descriptor;
        ...
    }
}

Is it possible to call static abstract interface member conditionally, without reflection?
