Openssl - G and P params value increase in DHE cipher

[preethi teekaraman <preethi.kavi17@xxxxxxxxx>]

Hi Openssl, 

I'm using the latest version of  openssl to create a self -signed certificate. 

My request is like, we need to observe G and P Param to 256 as value but we could see only 2 as value while a handshake happens between server & client. 

is there any option or command based solution to increase the G and P parameters? 

Regards,
