Downgrade OpenGL ES 3.x to ES 2

$ glxinfo | grep 'version'

server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
OpenGL core profile version string: 4.5.0 NVIDIA 375.82
OpenGL core profile shading language version string: 4.50 NVIDIA
OpenGL version string: 4.5.0 NVIDIA 375.82
OpenGL shading language version string: 4.50 NVIDIA
OpenGL ES profile version string: OpenGL ES 3.2 NVIDIA 375.82
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20
    GL_EXT_shader_implicit_conversions, GL_EXT_shader_integer_mix,

How can I change OpenGL ES profile to use version 2?

I tried install libcogl-gles2-dev and libgles2-mesa-dev. But the version used is stll ES 3.20.

In terms of development, OpenGL ES 3.2 is backwards compatible with OpenGL ES 2.0, so there isn't a practical reason to downgrade. If you want to support OpenGL ES 2.0 at a minimum, simply only use features that it supports.

If you're insisting on downgrading, you would have to install a (very) old driver that didn't support OpenGL ES 3.0. Depending on your hardware, such a driver may not exist. From the output, you obviously have an Nvidia card - you can find older drivers here. OpenGL ES 3.0 was released in August 2012, so anything dated before that likely doesn't have support for it. Again, I wouldn't recommend doing this.
