If I have ever needed to uninstall anything via terminal it works with this post from coderus

So this pkcon remove and then the program that you are trying to uninstall. Hardest for me was to find the correct name of the application... Because it needs to be exact correct. You can find all rpm packages installed in your phone via terminal (as root, write rpm -qa and this command shows all rpm packages that you have your phone has installed)

Please note that you need to know what you are doing. Please do not uninstall anything, that you are not sure.
