Does anyone know if the 3400G APU enables PCIe 4.0 like other Ryzen 3000 series chips? It looks like ASRock has enabled this on at least one of their motherboards, the X570. Sadly, I haven't found a single m.2 to PCIe 4.0 adapter.
No. The APUs are based on Zen+ and do not have an I/O die, so they are PCIe 3.0 only. As for 4.0 risers, high quality 3.0 risers should work as long as they are relatively short - PCIe 4.0 needs signal repeaters if trace/riser length gets too long.

it isn't Zen 2, it is basically a Ryzen 2 so as Ryzen 2 don't support PCIe4 I can't see the 3200/3400G supportig it either. And there are PCIe restrictions on the Ryzen Gs anyway.
