What to do might depend on why one is seeking a "de-Googled phone".
For example, all iPhones are "non-Googled" (except if the default search-engine deal counts as "Googled"; if so, that's easy to change).
GrapheneOS isn't really "de-Googled", because all Android devices run lots and lots of code that was contributed by Google to the AOSP project, which GrapheneOS is based on, and because 100% of the firmware on Pixel devices comes from Google. Also, the GrapheneOS team has done a lot of work to make it possible to run various Google services on GrapheneOS for users who wish to do that.
Here are three web pages with information about GrapheneOS:
