Recommendation for software to customize power profiles for AMD GPUs & save display config on root level

Back when I was on GTX 1060, I had NVIDIA’s X Server Settings to apply my monitors’ position config on root level. Now with Radeon + Plasma, I can’t do that any more. Any recommendations (preferably Qt)?

For configuring power profiles, I prefer a GUI app that also has a CLI mode that’ll allow me to script it (which I’m planning on doing with Plasma’s activity settings).

As a bonus, is there an overclocking tool for AMD GPUs, similar to Green With Envy for NVIDIA?
