@Michail71,

Not in the way that you would think.

This would be achieved via a Smart Action, however there is no available Trigger for a decrease or Increase in brightness. I also believe that there is no current smart action for dimmers that allows you to dim the lights by X%.

To keep the switches in sync, you would likely need to set scenes or smart actions to trigger based on a device turning on or off, but would rely on choosing a set brightness.

You may be able to achieve a "sync" by using another official integration, as I believe that smartthings has a feature to sync the state of a dimmer with the brightness of another.
