Is there a possibility to enable different specified values for each locale?
We are also interested in this, I’m commenting to revive the thread since no one has answered.
Hey @gerald and @technology, unfortunately this still isn’t a planned feature 
Please vote on it if you haven’t already, as that’s how the devs typically plan work.
In the meantime, you might be able to create similar functionality by writing a plugin, specifically a “field extension” that checks the value against the current locale and returns an error message (or toast) if it fails to validate: Field extensions — DatoCMS
It’s a hassle, I know, and I hope the feature request is added at some point. Sorry about that!
