Supporting OpenGL 4 on Android platform

Hi, I would like to build UnReal application targeting Android platform. But, I want to use the openGL4 library instaed of ES3 on Android. I ported the OpenGL4 library onto Android platform. Currently, I don’t see any option to choose openGL4 on Android platform from settings panel. I know In general we don’t have OpenGL support on Android platform, I got this specific requirement.

Is there any way to achieve this from Unreal Engine settings? (or) Do I need to make source code changes to support OpenGL4 on Android platform?

Please provide some guidelines in this regard.
