I know it is possible, but I forget the function, does anyone know?
It is possible, using SetCoreGuiEnabled
game.StarterGui:SetCoreGuiEnabled(Enum.CoreGuiType.Type,false) --[=[ Enum.CoreGuiType.PlayerList Enum.CoreGuiType.Health Enum.CoreGuiType.Backpack Enum.CoreGuiType.Chat Enum.CoreGuiType.All ]=]
