No OpenGL installed

Hi. I have a eReader that runs android and doesn’t have OpenGl installed. I want to know iif there is a way to install it. The model of the eReader is a Onyx boox M96, and it’s strange that doesn’t have OpenGl because another eReader I have of the same company, the Onyx boox C67Ml, has it installed.

I searched on github but it seems only have libraries but no installers.

If its not possible to install because it needs to much costumization, maybe I can extract from the other eReader model where it is installed and changed some attributes.
