Default [Q] Manual uninstall of flashed keyboard

Could someone please tell me how to manual uninstall of flashed keyboard? I installed RedMa7_keyboard_N2.zip and I've used a root file manager to locate the files in two folders, one META-INF and the other system folder. I'm afraid that if I just delete these specific files I may encounter FC errors. I searched this forum thread but did not come up with anything useful pertaining to my issue.
