GeForce RTX 3060 not working with Ubuntu 20.04

I have a new machine with RTX 6060 and Ubuntu 20.04 freshly installed.
after installation, it’s stuck at the motherboard logo I added kernel parameter acpi=off during grub boot so the screen is loaded and I could install SSH.
then I installed the driver 470 but still the same case.
nvidia-smi output:
NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
also, I followed those issues steps but nothing change

and here is the nvidia-bug-report

I did all the suggested steps but nothing new here is the new bug report

Sidenote: please delete /var/log/kern.log, it contains several GB of old nvidia error messages.

The nvidia driver is loading fine now, just too late. Please try embedding it into the initrd:
