Sort of. The datastore is schemaless, so each entity maintains its own list of what properties it has. If you read the entities and resave them without the entities you want deleted, they will not be stored. Note that this is different from a "NULL" entity - properties with values set to null are still stored. You need to completely eradicate the property from your entity.
