disabling of ECMQV and OCB in Visual C#

Hi All,
Looking at https://www.bouncycastle.org/specifications.html
There is a section referring to patents, specifically to the use of ECMQV and OCB algorithms.

I noticed there is a System Property that can be used for disabling: org.bouncycastle.ec.disable_mqv
However, I did not find a method of using this for the Visual C# DLL implementation.

Does anyone know how this can be achieved?

Thanks,
Justin
