New problems in an old thread

After using @Matthias Fulz's method (bumblebee without bbswitch + pm with powertop+tlp) its quite simple to run any software requiring nvidia. with his patch.

The problem is in preventing any other software from using nvidia when not run with optirun/primusrun. For example, any software that calls for EGL automatically turns on nvidia. Mpv is one of those.

Is there any way to ensure EGL calls intel instead? There is solution in arch wiki with env-variable "__EGL_VENDOR_LIBRARY_FILENAMES="/usr/share/glvnd/egl_vendor.d/50_mesa.json"
"

but it does not work. I have tried adding it in all possible places (/etc/environment, /etc/profile, bash-profile, zsh-profile-equivalent etc..)
