Edit 9/6 0820Zulu:
Addition 9/7: The sad state of Nvidia with all its money: These are not acquired quirks, but a fresh install of 20.04 on the NUC (as well as a seasoned 18.04 w/ 460 driver on a different machine) show these BUGS! They simply don't hit on a vanilla install.
sudo chmod 666 /var/lib/ubuntu-drivers-common/last_gfx_boot 664 not enuf to write; with 666 it CAN write last_gfx_boot.
sudo ln -s /usr/share/doc/nvidia-driver-470 /usr/share/doc/nvidia-driver-470-server - Add SymLink to account for directory bug.
sudo touch /run/nvidia_runtimepm_supported as it wanted to create it but couldn't.
sudo chmod 666 /run/nvidia_runtimepm_supported in case it wanted some file content.
On next boot some process was able to delete the file but the next one couldn't create it again.
I couldn't open last_gfx_boot for writing.
Stuck.
Sth seriously ****** up with permissions + the path bug.
Edit 9/5: Moved non-essential irks to the bottom.
@Nmath Edited to have the whole current config in one place, structured:
Don't ask me what I read and tried to get the Nvidia driver (470, latest) working on
- Intel NUC6i7KYK i915 integrated GPU and Ubuntu 20.04
- FHD monitor on the NUC's HDMI
- RTX 2070 in an HP GA1-10 Thunderbolt 3 case
- UHD 49" display (Samsung 2021 TV) on RTXes HDMI
BTW: Secure boot is off. (as suggested in other solutions and didn't make a difference)
With the Nouveau driver (and on Windows 10) the 2nd, UHD display works.
With the Nvidia 470 driver there is no second moni in Display Settings and the TV says "no signal".
After weeks of reading up and digging I'd hope I came across the right info now to solve it.

I couldn't open /var/lib/ubuntu-drivers-common/last_gfx_boot for writing.
Error: can't write to /var/lib/ubuntu-drivers-common/last_gfx_boot
On further digging today, 9/5:
/etc/u-d-c-nvidia-runtimepm-override really not there.
Correction: Re json file - guess bug: nvidia-driver-470-server directory is NOT there as I installed 470 w/o "server" in the name.
So there is a nvidia-driver-470/supported-gpus.json.
Worth trying a SYLK?
Also, nvidia-xconfig says there is no /etc/X11/xorg.conf and generates one.
A thousand thanks in advance for a solution!
G.
Non-essential itches:
On Ubuntu first some unrecoverable NUC firmware bug got in the way (Not on Windows!), but there is no newer BIOS.
Finally with an FHD display on internal HDMI and the UHD on the Thunderbolt 3 I discovered a boot problem, cuz boot from TB was on in the BIOS and the system was stuck waiting for TB boot when on.
Windows 10 has been working in ALL configurations! (I could circumvent the TB boot problem by switching on the external GPU with Win already up. Didn't figure the reason as long as I had only the UHD display on the internal HDMI and used the GPU as machine learning accelerator.)
