Hudlayout.res, set the "visible" and "enabled" values of "DamageCircleDot" to "0" (there are two "DamageCircleDot"s, one with those set to 0 and one set to 1).
I was using the default loadout screen, which is available in the /customizations folder. Same thing for the shortcut servers, just look for "Server Links Template" in main menu.
