Kill Shot on screen

Hello, since the lovely new ui… Certain settings are now gone.
Has anyone figured out how to disable the heads up notification for kill shot?
I know it used to be a floating combat text, spell aura setting. However that is no longer there.
It pops up anytime something hits the proper % for killshot. So blasting through old raids for my weekly mount runs… I am losing my mind, it is so annoying lol.
