Be warned that uninstalling system apps can at times have unwanted effects. So backup first.
There are quite a few apps which you can use to uninstall them. ES file manager definitely does (menu - > library - >Apps)
Others like titanium backup will let you too i think…
Or if you want to do it manually just delete the apk from the system directories…
I’d recommend to use Root Uninstaller and freeze the unnecessary apps, it has the same effect and you can unfreeze them in case there is a problem.
This (highlighted in red) is what i froze and didn’t cause me any issues:
