I am using HP 15-cu1004tx laptop with dedicated AMD GPU (RADEON R530).
I can't speak directly to your model. But many features are enabled for laptops in the drivers by the laptops maker. These features possibly will require a driver from HP to work. Did you get your driver from AMD or HP? With laptops you should always get drivers from the laptop makers if possible as they have modifications that may not be available in the AMD vanilla drivers. Hopefully someone with more knowledge will have a better direct answer. I would consider asking you question to HP support as well and also ask AMD support: Online Service Request | AMD
