When it comes to the Ryzen 2000 series. A Ryzen Power Plan is not necessary for the Ryzen (Zen+) 2000 CPU series.
Which the latest chipset does not install on its own, since it is not necessary. Windows balanced Power Plan will work perfectly fine.
If you were to upgrade to a Ryzen 3000 series CPU, you'll have to reinstall the latest chipset. Which will install the Ryzen power plan once the installation detects a Ryzen 3000 CPU.
