Can you back up this claim with some external documentation?
Or at least pointer the appropriate part of the code?
https://github.com/anholt/mesa/wiki/VC4-OpenGL-support says that the
VC4 hardware is a GLES 2.0 renderer and it would seem strange that
the mesa driver for it would not support OpenGL ES.
