Hello,
USB-C monitor output of UD22 doesn't use DisplayLink technology (this product is kind of a hybrid solution). For any potential updates of this functionality, please check UD22 FW updates published directly by Dell:

The latest version as of today is 1.0.17.23, A07, unfortunately, it requires Windows to perform an update.
Regards,
