Per test case http://iso.qa.ubuntu.com/qatracker/milestones/437/builds/255601/testcases/1718 the Nvidia proprietary drivers should be installed, independent of the network availability. Testing the 22.04 ISO released in April, 2022, the installer **did install the NVidia driver** (but not the nvidia-settings app, as the test case also suggests).
My device (Acer Aspire A515-52G-57NL) is equipped with an Intel i5-8265U processor (UHD Graphics 620) with a Nvidia GeForce MX130 GPU. I expected that, by checking the box "Install third-party software..." as instructed in step 6, I'd get the Nvidia driver installed. But that didn't happen in any of the two installation attempts I made. The system booted, enrolling MOK was successful, but there was only Mesa Intel graphics driver, thus the commands `nvidia-smi` and `nvidia-settings` could not run, suggesting a failure on steps 25 and 26 of the test case.
By manually installing `nvidia-utils-515` and `nvidia-settings` I could achieve the results expected in steps 25 and 26, but that required me (the user) enabling network and explicitly installing the required packages.
I wonder if the fact that the intel device is capable of displaying full graphics lead to the choice of skipping the Nvidia driver.
ISO used for the tests (the current one at the moment of this writing): https://cdimage.ubuntu.com/jammy/daily-live/20220809/jammy-desktop-amd64.iso
As said before, drivers did get installed when testing the Jammy Jellyfish ISO released in April.
