There are no Windows 10 AMD Drivers for your legacy APU.
Here AMD Support showing what AMD hardware is compatible with Windows 10 and has drivers to use: https://www.amd.com/en/support/kb/faq/gpu-615
If you had a A8-6xxx series APU then it would be supported in Windows 10.
When it mentions that Windows 10 is supported on HD6xxx series GPUs it is talking about the Discrete GPU cards (desktop and Laptop) not the HD6xxx Integrated Graphics of your APU.
So the only other solution is to install Windows 7 OS on your laptop and uninstall Windows 10. I wouldn't recommend installing Windows 8/8.1 since AMD doesn't support that OS anymore but still supports, for the moment, Windows 7.
