mb/novacustom/mtl-h/var/igpu/data.vbt: Disable secondary display feature

Currently, to make sure that the UEFI setup menu stays legible on HiDPI
displays, the VBT has the Fixed Display feature enabled with the
resolution set to 1920x1200.

If the secondary display feature is also enabled, and a monitor with
resolution lower than 1920x1200 is connected, the result is that neither
the internal nor external display is initialized.

Disable the secondary display feature to ensure that the internal
display keeps working regardless of any connected external displays.
