Help with Arc A770M in Nuc 12 Enthusiast

[TudoBem]

Is there any way to make all graphics pass through the A770M instead of the embedded Iris Xe?  I have tried older games that seem to refuse to use the discrete GPU instead of the integrated graphics.  I'm on Windows 11 and have even tried their 'best performance' setting both on global and individual app settings.  If I completely disable the Iris GPU in device manager, everything just renders on the CPU at about 2 fps (lol).  Any help is greatly appreciated.

Video over Thunderbolt requires the chipset to copy the image over PCI-e from the A770M to Iris Xe. If connected by HDMI or the 2 DPs at the backside, system can run without the integrated graphics, delivering some performance improvement (depending on game and resolution) but the idle power will increase by 10W.
