Console Command Help

I know there is probobly about a thousand topics with the same question but I could never find my answer. I was going to make a video, but there are some weapons (Ex: CSS Weapons) that have special sights that don’t go away when you use cl_drawhud, I remember that there was a console command to hide it, but I can’t find it. I also need a console command that hides the Kill Icons for whenever someone is killed. Help?

“hud_deathnotice_time 0” will get rid of the kill icons.

Thanks, but I still don’t know how to get rid of the green aiming sight for CSS weapons.
