Eco button / GPU button doesn't work on my Akoya P6625.

I've installed the hotkey drivers, then the Graphics drivers for both the Intel IGPU and the ATI GPU (both through Windows Update as they were newer) and then the "EcoBtn" driver. But when I press the GPU button it doesn't do anything. The only way for me to switch is to manually go into Device Manager and enable the GPU and then disable the Intel IGPU and then disable the extra bugged monitor that appears.

I am on the latest x64 Windows 10 Pro build 22H2. 

Updated everything via Windows Update.
