There is no Official version for this device.
The unofficial version has the same amount of de-googling as the official ROMs for other devices - i.e. All the default installed apps have been de-googled by /e/
My Custom build doesn’t do any extra de-googling. It differs from official and unofficial ROMs as described in this post
The new and replacement apps in my custom builds are all from F-Droid, are unmodified by me, and are open source. No de-googling has been done, but I don’t believe that any of them make much use of Google’s services or send any information to Google’s servers. If you are worried that they need de-googling, then you should stick to the unofficial build.
Both the unofficial and custom ROMs are available from my AndroidFileHost account

The extra launchers in my custom build (Omega and Lawnchair) are not part of the OS - they are extra apps installed by me for my convenience. The Bliss Launcher is part of the OS and is degoogled by /e/. If you don’t want any apps present on the phone that have not been degoogled by /e/, then don’t use my custom builds, (and don’t install any apps from /e/'s Apps store. /e/ **do not degoogle the apps that Apps serves)
