For me, RADXA POWER PD 30W is sold out right now. Since I still want to use my PD chargers, I found out that using YZXSTUDIO’s ZC828 (which uses the Zhirong SW3518S chip) as a relay (PD in, PD out, it also supports DC input) can make it work on every PD charger that I have. It can negotiate 20V very quickly and is reliable. I will use this as a temporary solution until a stable U-Boot firmware solution is available.
