  If you're brave/looking for a challenge, it looks like some Chinese hobbyists have been working on fixes for the Xiaomi RedmiBook Pros, but personally, if I was going down that route I'd try to hunt down a Mechrevo Code 01 2.0 instead.

  Adjust power management settings for Ryzen APUs

  The H and U CPUs are typically binned differently - the former for being able to boost a bit higher and the latter being a bit more efficient, but due to the process maturity, there probably isn't all that much difference between them. In my experience, my H CPUs seem to perform about equivalent to a U CPU when set to similar TDP settings. You can use a tool like https://github.com/FlyGoat/RyzenAdj to easily set the max TDP you want. This is a bit older doc (covers mostly Ryzen 4000) but does a good job summarizing how AMD mobile CPUs do their power management: https://github.com/FlyGoat/RyzenAdj/wiki/Renoir-Tuning-Guide (if you want a summary of how Intel mobile chips work, I've written a guide here: https://github.com/lhl/linuxlaptops/wiki/2022-Framework-Laptop-DIY-Edition-12th-Gen-Intel-Batch-1#cpu-measurements)
