How to Increase number of NVENC concurrent sessions

I want to know how I can increase number of NVENC sessions from the single Computer. I know currently with single GPU max sessions achievable is 3. Is it possible to increase that limit by adding more GPUs to the machine or doing API changes ?

Hi,
Please refer Video Encode and Decode GPU Support Matrix [NEW] | NVIDIA Developer to identify GPUs that can support more than 3 concurrent sessions.

Thanks.
