NO external display on UHD630 + MacBook PRO 16.1 SMBIOS with DGPU turned OFF

Hi!

I got an xps9700 4k gtx 2600 with latest macOS (ventura and sonoma) working great. 15w idle. OC9.4

As expected , sound, sleep won't work. but external monitor also dosn't work wich I was ok until I bought a usbc monitor for WFO purposes.

Now , I've read somewhere that when turning off dgpu it's not possible to output to external monitor as Macbook pro 16.1 expected the external monitor to be driven by the dgpu. If I enable (remove the disable gpu weg) AND remoge de disable DGPU SSDT to lower power consumption , the monitor output is working great. But at the cost of havin a 50w idle power management....

Then I did try to use a non dual gpu SMBIOS (macbook pro 13 2020 (macbook pro 15.2 if I remember) and everything was working great BUT the USB ports don't work AT all...

1- Do I need to remap my usb ports if I use another SMBIOS? Is there any downside of using a macbookpro15.2 SMBIOS for a 10th gen CPU?(did a nvram reset and all that stuff beforehand)

2-Is there another way to use the best SMBIOS wich is macbookpro16.1?

thanks guys! and if somebody have a working sound for the XPS 9700 this would be amazing ;) ALC711
