It is loaded by default by /Library/LaunchAgents/com.adobe.AdobeCreativeCloud.plist.
If you run
launchctl unload -w /Library/LaunchAgents/com.adobe.AdobeCreativeCloud.plist
that will disable it for your user.
To turn it back on
launchctl load -w /Library/LaunchAgents/com.adobe.AdobeCreativeCloud.plist
it still is in the background despite doing that, and after deleting the files in LaunchDaemons and LaunchAgents
edit: I did not even launch photoshop(or anything adobe) for the past 4 boots
