Dell Smart Dock TB5 activates USB Ports when i unplug the usb-c cable from my laptop

Hello,

ich have a not so fine behaviour with my Dell SmartDock TB5 SD25TB5. When i end work and unplug the laptop from the docking station, the docking station activates the usb ports on the dock without a laptop connected.
The USB Ports and all other ports are off after shutdown of the laptop but pulling the cable results in activated USB Ports and therefore active mouse and keyboard (can be seen because they are luminating).
Mouse and Keyboard are attached to the USB-A Ports with Powershare but there are no Ports without Powershare and at this point i am lost.I am running a Dell XPS with ubuntu 22.04.
Is there maybe a way with windows to deactivate the powershare feature on some ports?
