ROG STRIX X870E-E GAMING Wi-Fi iGPU Multi Monitor support?

Hi, as the title suggests, I wasn't able to connect a secondary monitor with the USB-C DP while using the dGPU. In the BIOS settings I find only two options:

Advanced → NB Configuration

Primary Video Device: PCIE Video
Integrated Graphics: Force

There's no iGPU Multi Monitor support voice. I'm on latest BIOS (1701). LEGO firmware updated to V0203. CPU is a AMD Ryzen 7 9800X3D.

The AMD iGPU is active and functioning in Windows (I can see it from Device manager and can access to its driver configurator).
When I use the USB-C cable, a portable monitor I own receives energy but no video signal. Can't find the monitor listed in the monitor manager page on Windows either.

Cable and secondary monitor are tested and work as intended in a Multi Monitor setup with an older Z670 ASUS motherboard.

How can I enable iGPU Multi Monitor with this mobo?
