Disable Image Effects In One Place?

Is there somewhere I can disable image effects completely without having to individually pick and choose effects on different cameras? I’m developing a cross-platform game which must use image effects on Windows and Mac, but many of the image effects don’t work on Android. Several, in fact, just render a completely black screen instead, which isn’t great. So I’d like to switch them off completely, but it would be nice if there was an overarching variable somewhere which would stop the engine even trying to use one, without having to make changes to assets or levels (of which there are many.)

My first instinct was too look for quality settings, but Android seems to ignore quality settings, so that won’t fly. Since most of the image effects are supposed to not work without OpenGL ES 2.0, I tried disabling that, but I still get black screen and garbage drawn all over the screen with some image effects so that’s not working either. Is there some way I can do this across the board? It’d be really ugly to have to have scripts with #if#endif sections disabling the effects on each different camera in each different scene.

Not possible then, I guess?
