You could edit its launcher. The launcher configurations sit in /usr/share/applications
so you can run sudoedit /usr/share/applications/blender.desktop
and change its Exec
statement so you end up with something like this:
[Desktop Entry]
Name=Blender
GenericName=3D modeller
GenericName[es]=modelador 3D
GenericName[de]=3D Modellierer
GenericName[fr]=modeleur 3D
GenericName[ru]=Редактор 3D-моделей
Comment=3D modeling, animation, rendering and post-production
Comment[es]=modelado 3D, animación, renderizado y post-producción
Exec=optirun blender
Icon=blender
Terminal=false
Type=Application
Categories=Graphics;3DGraphics;
MimeType=application/x-blender;
As dobey suggests, you can also make changes in the user ~/.local/share/applications
directory. This will make the change for only this user, instead of globally (if you have a multi-user system). Keeping a copy of your changes locally is a good idea if you'd like to make them more upgrade-proof. Be aware that changes in the local directory won't automatically reflect changes made by upgrades to the main configuration file (for example, arguments to Exec).
