Config option needed for "disable HDMI monitor detection and force connected status"

[nlazovic]

My QML application (no ui, does offscreen rendering) fails on start with "Segmentation fault", if no monitor attached. Runs fine if monitor is attached before app startup.
I need to be able to run QML application without monitor being connected to board. Currently getting "Segmentation fault", if no monitor attached. Works ok if monitor is attached.

I am looking for a way to disable HDMI monitor detection and force connected status, similar to Odroid XU4 settings, example
   # HDMI Hotplug Force (HPD)
   # 1 = Enables HOTPlug Detection
   # 0 = Disables HOTPlug Detection and force the connected status
   setenv hpd "0"

Any info is welcome.

My setup is QT 5.9.3. or 5.10 on Asus Tinker board with latest OS (Latest version v2.0.4 - Debian stretch based. 2017/11/15)

Thanks
