you are here because you want to disable the fprintd ; fingerprint daemon on your machine. short answer is you cant.
long answer is it is isnt a service that you can enable or disable it is called by dbus when there is a need for it. i did discover a method to disable that part of it in this thread but you know what? i like a suggestion in there too
yum -y erase fprintd
and i am a happy camper! :D
