Phandelver isn't available in component parts. (In contrast, you can buy the individual monsters and magic items from Storm King's Thunder, for instance.)
So, maybe, maybe not.
In any case, we have no choice but to wait, unless WotC wants to come out and say "so, remember how you were all worried about microtransactions last year? It turns out, absolutely not."
I can see à la carte purchase options for Phandelver the Shattered obelisk. Not for book of many things, though.
