We do not want any of our users to create custom actions. We have made it so the feature doesn't work but we can't seem to find a way to remove the lightning bolt through the SDK. We are in the progress of upgrading from 9.5 to 10.1. It would be ideal if we could solve this for both versions.

Can we remove this lightning bolt?
