The project build for a VR project keeps adding assets to package that are not being used

Hello Unreal Community!

I have a VR project which i build for quest 2 earlier but i don’t know for whatever reason after i change “shader 5” model to Android ES 3.1

The issue occured that the engine is packaging additional assets which i do not need and due to that the file size exceeds
is there a way to revert back to that or how do i fix this issue!

Thank you so much for your help i appreciate it.
