Are you using the Save and Load methods of blackboards which uses Unity PlayerPrefs for saving and loading with a key?
If so, an entry from Unity PlayerPrefs can be deleted using the Unity PlayerPrefs.DeleteKey method.
If you do not provide a custom “key” name for when saving, then the “key” will be the blackboards name property; thus you can for example call PlayerPrefs.DeleteKey(blackboard.name);
