Mystery. Nuc recognizes two monitors but I only have one. (Nuc8i5beh+Egpu)

[Totuccio28]

Hello,
sorry my english translated.
I'm asking for help from you because I can't solve a problem.
I have an intel nuc8i5beh and an egpu aorus gtx 1080 box connected in thunderbolt.
It all works beautifully with excellent performance.
The only flaw I can not manage the display.
Connection thus composed.
Nuc with thunderbolt at Egpu.
Egpu with DisplayPort to the monitor.
From Windows I see two displays.
If I set the second monitor as primary (egpu) at start up I don't see the bios.
I view the desktop directly.
How do I best manage this situation
and connect only the egpu displaying a single monitor and see the bios at startup?
The nuc shows me two monitors having only one connected. I don't understand why and how to remedy this situation.
Thanks in advance to all of you for your support.
