Disabling KDE Connect Service

[bancfc at openmailbox.org]

Hi. I'm an anonymity OS dev (WhonixOS) and we use KDE as our main DE. I 
noticed KDE Connect has been recently enabled by default on Debian 
Stretch.

For hardening reasons we run only the barebones services needed by our 
users to reduce attack surface. How can I disable the KDE Connect 
service? I haven't found any related service under the systemctl unit 
files listing.
