First check if your HDMI and Type-C ports are connected to Intel or NVIDIA.

Hi,

Yes, I checked that,
I'm opened the my windows 10 and disabled my NVidia GPU and my 2 external monitor still working on Intel UHD 630
Also, Big Sur detected my Intel GPU "Intel GPU 630 1536 MB"

You're still not clear what port is not working.

HDMI?
DP?
USB Type-C?
