AMD has drivers for their 7th generation A4-9120 laptop processor but yours is a OEM 8th Generation laptop processor. so you would need to go to your laptop manufacturer to get drivers for your APU.
But you can try AMD A4-9120 AMD Driver and see if it works or not. Make sure to make a Restore Point in case something goes wrong. BEFORE installing it from here: https://www.amd.com/en/support/apu/amd-series-processors/amd-a4-series-apu-for-laptops/7th-gen-a4-91...
