Same solution for pre or post installation.
Your graphics must be configured correctly in order to function.

Hello, I have correctly installed big sur by applying the patches to the video card, now I have the problem of the second monitor, do I need to change something on the connectors in the config?

Probably.
There is sometimes a setting in the BIOS for Multiple Monitors, could be worth checking.

Other than correctly configuring your video ports, no.

You're not using the VGA port are you ? VGA is unsupported.

Edit : Try the igfxonln=1 boot argument.
