Gimbal vibrations

Hi all,
I’ve been testing my gimbal and I can’t make the vibrations disappear. They are not very exaggerated but they are very annoying. I wanted to know what I can do. Here I show you some photos and flying footage to see it clearly, thanks!
My setup is:
Gimbal: Arris Zhao Yun Pro
Camera: Sony a6000
Frame: Tarot X6
Motors: DJI E1200
Battery: Tattu 6s 12.000mah
Controller: Pixhawk 2.4.8

Is there a manual or docs for the gimbal? Or an email address where you can ask the manufacturer? That’s what I would try first.
