Anyone been able to find the alternate mixes of tracks (i.e. with no vocals) that are NOT on the OST itself anywhere?

[The Everlasting Stillness ☯]

Like for example, Une vie a t'aimer with no vocals, or Golden Harvest's BGM with no vocals (plays only before reaching the 1st Expedition flag), or the battle end themes?
Haven't even finished the game yet, nowhere near probably, but I've found quite a few tracks like this that are missing and it's a tragedy. Reminds me of NieR Automata, but at least that one got a proper unmixed layers rip later on.
