Bug description:
  [ Impact ]

   * On Dell K2 Dock, flashing the Dell provided DFU firmware cab file

   * Flash DFU 01.01.13.01 by fwupd tool  1.9.33-0ubuntu1~24.04.1ubuntu1
  on noble and  2.0.17-6~25.10.1 on questing

   * Terminal Show update successfully

   * Run command 'fwupdmgr get-devices'.

   * Found NVM can’t update to 64.81

  [ Test Plan ]

   * On Dell machine which supports TBT5

   * Flash DFU 01.01.13.01, run command "sudo fwupdmgr install <DFU
  firmware>.cab --allow-reinstall"

   * if the test cab is missing signature, below message will pop-up
     firmware signature missing or not trusted; set OnlyTrusted=false in /etc/fwupd/fwupd.conf
     ONLY if you are a firmware developer

   * run command "fwupdmgr get-devices" can get correct firmware version

  Additionally, the standard testing under “QA Process” from
  https://wiki.ubuntu.com/firmware-updates will be followed.

  [ Where problems could occur ]

   * The SRU requires the version bump to 1.9.34 by leveraging the exception document
     https://wiki.ubuntu.com/firmware-updates

  [ Additional information ]

   * The upstream commit for the issue, https://github.com/fwupd/fwupd/pull/9784
   * The version bump to 2.0.20 for questing adds new feature https://www.linuxtoday.com/blog/fwupd-2-0-20-adds-amd-uma-carveout-support/, which is enabled for kernel >= 7.0, it won't be enabled on questing since non off questing kernel support it.
