There are PhDs with multi-million dollar grants who cannot do it. I mean let's say they did somehow figure out an enzyme to speed it up, it would likely cost more than just supplementing more of the desired precursors. There might be some obscure food or supplement that does what you want but it will cost more because it will be rare and then you've got the problem of huge consistency between batches because all manufacturing in China/India is the wild-west. Easier to just take the precursors which are mass produced so prices slowly coming down, though covid/inflation/supply-chain threw it a curve.
