I haven't been able to find any information available to unlink an account that has been linked with cross save. I don't need to do this but having this option available can be very helpful for others. What happens if you lose your iPhone or Android? If you no longer have access to the Apple ID or email is there a way to disable that part? Or if you lose your PS4 account is there a way to remove the Lost account and assign a new one to your primary account?
