I have no interest in using spiceproxy. Is there a way to disable it cluster wide? No need to have features/resources enabled/running if you are never going to use them.
If you want to enable it again make a link from:
/etc/systemd/system/multi-user.target.wants/spiceproxy.service -> /lib/systemd/system/spiceproxy.service
Yes the sub button on the console button still shows spice and users can choose qxl as a display (which is needed for spice) but no connection can be made.
So no problems besides that it's shown, AFAIK.
