Dear @Konstantin-Kolesnichenko, This behaviour has got nothing to do with the 2.0 version. It's the same in the previous version of MySensors. Node's need communication with the gateway before they can start. I'm closing this topic. See https://forum.mysensors.org/topic/4449/how-to-disable-default-node-registration-to-the-gw/2. It's a thread about the same topic.
