UD22 - Doesn't work properly after A07 update

Hello community,

Yesterday I did the firmware update of my Docking station Dell UD22 (to try to solve performance issue with triple screen setup) to the latest (it was launched yesterday, according to the drivers/firmware page) and after the update the HDMI port stopped to work and the Power Delivery was reduced to the point that the computer (windows 11) now reports "Slow charging". I've tried to downgrade, but the software doesn't allow to go back.

What I would like is to know if there's a way to revert the firmware. Any help?
