Brightness control of new Ryzen GPUs is properly supported by Linux kernels starting with the 5.8 version.

This version will get into Ubuntu 20.04 with a HWE stack.

Currently you can install the 5.8 kernel by running

sudo apt install linux-generic-hwe-20.04-edge

You will run the 5.8 kernel after a reboot.
