So there is definitely a consumable that unlocks them all. What I'm not sure of is when you receive it. I noticed it in my inventory after the full completion of the Wing of the Gryphon quest.
I first did scribing intro on Max template char and was confused why I don't have everything.
Then there is scribing template, I made it and used scribing consumables it had, then ported to that scribing area and I had everything.
