Black screen on boot after Nvidia driver install

Hi. I am using Ubuntu 20.04 (forced because we use an older version of ROS2). I got an error “unknown chipset” error from Nouveau when trying to install Ubuntu, and used this workaround to install: Fix "Unknown Chipset" with nouveau · GitHub

Now, whenever I install an Nvidia driver (been trying different versions, but currently on 560), I get black screen on boot. HDMI not outputting anything. Here is bug repport: nvidia-bug-report.log.gz (370.3 KB)

The issue is with your 13th gen intel igpu which needs a more recent kernel and firmware to work.
