Unattended Upgrades - could not be installed automatically

I have a pretty fresh install of Ubuntu 20.04 and don't remember specifically installing unattended-upgrades, but it seems enabled. As part of the MOTD when logging in I see:

16 updates could not be installed automatically. For more details, see /var/log/unattended-upgrades/unattended-upgrades.log

cat /var/log/unattended-upgrades/unattended-upgrades.log reveals these are nvidia-driver packages.

However, I'm not able to update any of these packages and it seems as if they're all the latest version.

$ sudo aptitude install nvidia-driver-465
nvidia-driver-465 is already installed at the requested version (465.19.01-0ubuntu1)

I'd like to keep unattended-upgrades, but seeing this message is driving me nuts. How can I get unattended-upgrades to recognize that everything is up to date, or how can I update packages that already appear to be up to date?

I eventually found the pin in /etc/apt/preferences.d

ls /etc/apt/preferences.d
cuda-repository-pin-600

Which seemed to be leftover from a cuda install I didn't really need. So I purged the cuda install, and removed the pin.

sudo apt purge cuda*
sudo rm /etc/apt/preferences.d/cuda-repository-pin-600
sudo apt autoremove
sudo apt autoclean

And then was able to update the (still installed) drivers using unattended-upgrade

sudo unattended-upgrade -d

after installing the driver updates and rebooting, nvidia-smi still works
