"cruncherEnabled=false" for android cordova builds

My builds for android are failing because I have some jpg images that cannot be processed by png crunch.

Even highly optimized png would be way heavier than jpg for those pictures. So I’d prefer to stick with that format. Beside, I have already optimized my pngs… So. Is there an option to avoid that ?

I guess that it should be set with App.setPreference( ); But I do not find what I should pass.

(And I did not find it there : https://cordova.apache.org/docs/en/dev/config_ref/index.html#preference )
