How to remove MDM config?

Can't seem to successfully remove the MDM config file after processing it. It still exists even after removeObject has been called.

Snippet below:

var keyToRemove = "com.apple.configuration.managed"
UserDefaults.standard.removeObject(forKey: keyToRemove)
      UserDefaults.standard.synchronize()
       
      if UserDefaults.standard.object(forKey: keyToRemove) != nil {
       print("Key \(keyToRemove) still exists after removal.")
      } else {
        print("Key \(keyToRemove) has been removed.")
      }

I'd like to delete the mdm config after processing it.
