在`/ lib / systemd / user`文件夹中禁用systemd服务

I'm trying to disable some services like gvfs-gphoto2 and others, as I use Manjaro KDE distro and removing these packages weirdly remove Network Manager. The init files for these services are on the folder /lib/systemd/user, so I tried to disable them with systemctl disable --user gvfs-gphoto2.service, or with --global, but no option for systemd worked. Is there a way to disable permanently the services on the /lib/systemd/user folder?
