Seems this can't be found yet...?
I want to do 3.4 20021, but want that file like you said.
I just upgraded my Edge to build 20021 (mainly because of new 1.19 maps), everything is fine, though people on F150 forum reporting bugs like Nav not storing favorites and source changing from USB on its own after restart.
This is reformat files needed and all of those are available now on russian Focus forum (I downloaded them from there):
