Not really I assume. There is no way you tell apart one binary executable from another if it wants to open a window or not until you started it (or of course read it in it’s documentation).
I would have removed the patterns for those desktops (and not bluntly all packages that by incident start with a string that might indicate or not that it belongs to the group you want to de-install. Same of course for the pattern X Window System.
OTOH, I do not understand quite what you want. Not enough disk space in your root partition? Else leave all those packages just as they are. Simply set your default target to “Multi user System” and you are done.
If you really want to get rid of all X/Desktop packages, you better re-install as a Text Only system from the beginning (but even then I am not sure that there will be no GUI applications installed, maybe some, like YaST, can run CLI and GUI).
Try opening YaST2-Software, then the “Package Groups” tab, if I understand correctly you want to uninstall all the packages in the categories from “Education” to “Publishing” with the possible exception of “Programming”?
Yes, I looked and saw there is not a pattern for KDE.
And yes, removing the pattern will only avoid that on the first update or install, YaST/zypper will install anew all the packages listed in the pattern.
In any case, just removing packages with names xyx* might remove a package that by incident starts with zyz, but has nothing to do with a other packages that by incident use this as a brand name. Changes are small, but not nil.
OTOH, many KDE programs do not have names that start with kde, like kmail, kaddressbook, dolphin, etc., etc. I assume same is true for Gnome, etc.
I really wonder. You take a system that you have filled with software of several DEs. I assume for a reason. As I see it, now you want to use that system for a different purpose, that requires a complete different set of software. Why not install your system in a way that it fits it’s goal? All the finding out and try and error (mind the last word!) you are doing now will probably take much more time with a doubtful result.
