ASrock AMD All-in-one with VGA Driver will install both the motherboard's AMD CHIPSET and AMD Integrated Graphics if you have a APU installed.
I would first install ASRock ALL-in-1 CHIPSET (to prevent any problems).
Update your BIOS to the latest and then update & download from AMD Download page the AMD B350 CHIPSET from here: https://www.amd.com/en/support/chipsets/amd-socket-am4/b350.
If by installing the All-in-1 ASRock CHIPSET removes your current AMD Graphics driver then you can re-install the newer version afterwards.
Make sure to follow this basic method to remove your current AMD driver to prevent conflicts:
Uninstall the current AMD Driver using DDU as per this method:
It could be due to a corrupted AMD Driver installation.
Download free program DDU (Display Driver Uninstaller). Run it in Safe mode with the internet disconnected.
You can also run it in Windows Desktop but then you would need to Reboot the computer for DDU to finish erasing all of the AMD Driver traces from your computer.
Once it finishes uninstalling the current AMD Driver in Safe mode and boots back to Windows Desktop, still with the Internet disconnected, delete the AMD Installation folder C:\AMD if it was created before.
Now install the full AMD Drive package you downloaded manually from AMD Download page. Not the express package. Run the package and if it installs correctly again delete C:\AMD folder and reconnect the internet.
This should prevent any conflict when installing the new version from the previous version.
By the way, C:\AMD is always created whenever you run the AMD Driver package
