Photoshop CC2019 silient uninstall

So I have more mac´s that are running CC 2019 Photoshop version 20. I would like to remove that silently and then upgrade to latest.

To upgrade to latest I have no problem do it. 

But How do I silently uninstall the old version. I could of course just remove photoshop in application folder, without doing a proper uninstall, but guess that can give issues etc when installing never version - and are settings than also lost doing it that way?

From adobe desktop cloud there is a uninstall tool, but it keep on asking if I would like to keep settings or not. If just I could find the paramter for that setting, and could do a simple script paramter so everything will happen smothly in the background.

Any input?
