Hero XI here. I found out how to do this.
(I do NOT use the Armoury Crate or ever installed it. So it is NOT in my system)
First, turn off control in Aura of anything connected to it. Then uninstall Aura. Use the cleaner to make sure it is gone.
In the Bios, make sure under AI section that Aura is on. I use Aura only in working state.
Open iCue, enable add-on's in the setting section.
Immediately my Asus 2070 Super and my Hero XI board showed up. I NEVER could get my board to show up in Aura. I can control both and the RGB strip that is attached to the board.
Interesting side note. When booting my board, GPU and RGB strip will still use the pulsing blue profile from Aura will booting. As soon as iCue starts up at boot, it takes control. Must be a hidden file somewhere that the MB, GPU and RGB strip reads from during boot.
Hope that helps.
