I have an application based on VTK 8.1.0 which only runs with OpenGL ES 3.0 Mesa 19.2.8 (Ubuntu 18). I want to run it in ubuntu 20 but the problem is that the version of opengl library is OpenGL ES 4.6 Mesa 20.0.4. Is there a way to run my application on ubuntu 20 with OpenGL ES 3.0 Mesa 19.2.8? I mean is possible make an upgrade of that libraries or run that application with a old version of opengl binaries?

Adicional information:

Example laptop on Ubuntu 18:

$ apt list -a libgl1-mesa-dri

libgl1-mesa-dri/bionic-updates,now 19.2.8-0ubuntu0~18.04.3 amd64 [instalado, automático]  
libgl1-mesa-dri/bionic-security 19.2.8-0ubuntu0~18.04.2 amd64  
libgl1-mesa-dri/bionic 18.0.0~rc5-1ubuntu1 amd64

Example laptop on Ubuntu 20:

$ apt list -a libgl1-mesa-dri  
Listando… Hecho  
libgl1-mesa-dri/focal,now 20.0.4-2ubuntu1 amd64 [instalado, automático]libgl1-mesa-dri/focal 20.0.4-2ubuntu1 i386

Thanks in advance
