More updates:

I removed nvidia drivers as described here https://askubuntu.com/a/757256/754424 . Ofc without nouveau.modeset=0 it doesnt boot.

With nouveau.modeset=0 it boots ("Software and Updates-> Additional Drivers" shows "Using X.Org - Nouveau" as checked, but I think Nvidia GPU is not up. "sudo lshw -C video" shows UNCLAIMED on Nvidia).

With nouveau.modeset=0 and without "options snd-hda-intel dmic_detect=0" the system freezes on the login or immediately after login. The login screen looks kinda bad, the same as when I booted with 5.8 kernel.

The above tests were with 5.4 kernel.

Now I repeated the last test with 5.8 kernel. It boots, does not freeze, but speakers show Dummy output and mic is empty. (So the same as before disabling Nvidia and using 5.8)

----------------------------------
I think this means that Nvidia GPU is not the cause of the freeze but audio. The 5.8 does not load microphone so the system does not freeze. Also WITH dmic_detect=0 and 5.4/5.6 kernel the mic is not loaded so the system does not freeze.
