If you absolutely need it, use a separate uC / “trigger” chip for PD negotiation.

I think the GP's point is that this requires a 12V-capable USB power supply.

I have converted pretty much everything I have to USB-C, from toothbrushes to old laptops, and am very happy with the results. My solution is to only own high-quality power supplies with good support for PD. Having done this, the question "Why isn't this thing charging?" doesn't really arise.
