Yes, get a reference to the volume component, it has a effect list, there deactivate bloom and mark the postprocessing volume dirty (the removeEffect method currently doesnt check effects in the sharedVolume which is the case for you i believe, this will be fixed in a future version)

    await delay(100);
    const pp = findObjectOfType(Volume);
    if (pp) {
        const bloom = pp.effects.find(e => e.typeName == "Bloom");
        if (bloom) {
            console.log("Found bloom");

            await delay(1000); // for demonstration
            bloom.active = false;
            pp.markDirty();
            
            // this will be fixed for effects in the shared volume:
            // pp.removeEffect(bloom);
        }
    }
});

Thanks I will test this now, will it work the same for enabling it again? I’ll test and feed back here

is the fix in 3.48.0?

yes it is

The script doesn’t find Volume in the scene - I am using BloomEffect.ts

however just finding the bloomeffect end enable/disable on it works fine!

Volume is what is managing all the postprocessing effects so it must be in the scene

I’m only using the BloomEffect.ts component in this scene which is odd, no Volume component I have manually added either.

Aaah got it, sorry I was assuming you had the Volume component in the scene.
