Ubuntu fresh install (22.04) with Dell's external sources

I want to do a fresh install of ubuntu 22.04 (especifically xubuntu) and after installation add the source lists I have in 20.04 for dell packages.

My hardware (Optiplex 3090 Micro) is targeted with version focal-somerville-ygritte.

My questions are:

There will be a jammy-somerville-ygritte? The existent jammy-somerville is compatible with my hardware? Or I don't have to upgrade the external sources' version, just add the 20.04's sources lists as they are now (referencing focal)?

AFAIK those packages are just for energy optimization, maybe an alternative its don't have them installed.
