Remove Sandtimer icon from loading screen between changing levels? (CV1 Rift)

How do you remove the Sandtimer icon during the black loading screen when a new level is opened? (by the way this is not a streaming level) I prefer the player only seeing total black. Because this project is some kind of immersive animation videogame i do not want interuptions that have nothing to do with the experience. Thanks for the help! I work with the Oculus Rift CV1.

My specs:

Oculus CV1
GTX980TI
Intel 4790K
16g Ram
SSD.

Does someone has some ideas for this problem?

The sand timer is part of the Oculus Software not UE4

I understand that it is Oculus, but it is strange that Ue4 allows the headset to run it’s own loading screen within the content?
