Disabling WvW's "Objective Captured" Pop Ups

[Moopliss.9520]

i've been playing the game with little to no HUD enabled the past several months, it's my favorite way to play the game thus far after playing the game since the beta days in 2012. for context, my skill bar and names of enemies only appear when i am in combat, they'll disappear once i am out of combat.

however the one pop up notification that i can't figure out to disable is the "Objective Capture" pop ups in WvW. these are the messages that appear on the center of your screen when a camp or tower is captured by your team or the enemy.

is there any way to disable these from appearing on my screen?
