Micro Studio Camera 4K shutter speed

i use a Blackmagic Micro Studio Camera 4K and a DeckLink SDI 4K 6G for get a live video with 4k resolution.
i need to increase the value of shutter speed more then 1/50 that is the max value on Camera setup, i need to set it about 1/6 .
there are some way to do it : firmware upgrade...
I use DirectShow api on my application.

1/6 shutter?? This will give you ghostig effects from h*ll

1/50 is normal shutter for every camera. 1/25 is giving a bit stuttering image when something moves..
1/12th is not nice to see anymore..

But the camera does not even support anything under 1/50 shutter. It has 15 different shutter speeds from 1/50 to 1/2000 sec.
