The nvidia-dkms will be installed when installing nvidia driver through "Additional Drivers"

[jeremyszu]

[steps to reproduce]
1. Install Stock ubuntu 20.04.3 on XPS 15 9510
2. Installing without using "Third-party packages"
3. After installation completed, launch "Software & Updates" -> "Additional Drivers" -> "Using NVIDIA driver .... 470"
4. dpkg -l | grep nvidia

[Expected result]
It should use pre-signed nvidia driver instead of dkms
e.g.
linux-modules-nvidia-470-5.11.0-27-generic
linux-modules-nvidia-470-generic-hwe-20.04
linux-objects-nvidia-470-5.11.0-27-generic
linux-signatures-nvidia-5.11.0-27-generic

[Actual result]
ii nvidia-dkms-470 470.57.02-0ubuntu0.20.04.1 amd64 NVIDIA DKMS package

If I installed nvidia driver during the installation by selecting "Third-Party packages". It will use pre-signed driver instead.

Please consider to use `ubuntu-drivers install` which will handle the corresponding actions. (e.g. prime-select, enabling RTD3)

This bug was fixed in the package ubuntu-drivers-common - 1:0.9.3

---------------
ubuntu-drivers-common (1:0.9.3) jammy; urgency=medium

  * UbuntuDrivers/detect.py,
    ubuntu-drivers:
    - Provide helper functions for NVIDIA on the desktop:
      o get_desktop_package_list()
      o nvidia_desktop_pre_installation_hook()
      o nvidia_desktop_post_installation_hook()
      The new functions, which are now used by ubuntu-drivers
      (only for the desktop i.e. "ubuntu-drivers install"),
      allow reusing the hardware detection and the customisations
      from ubuntu-drivers in other applications such as the
      Software Properties UIsi (LP: #1942208).
    - Add the "--recommended" option to the "list" command
      (LP: #1952147).
      This allows to show only the packages that will be
      installed using auto-detection i.e. one specific
      driver and its kernel module, instead of all the
      compatible drivers.
      This works with and without --gpgpu, yielding different
      results.
