No, as the Nvidia dGPU isn’t supported by macOS.

There are some recent developments with the help of AI that are looking to get Nvidia RTX cards working in macOS, but they aren’t ready for general consumption.
 
Yes, you can run the system with no graphics acceleration (nominally VESA mode), but you may have some graphical artefacts and glitches to deal with when doing so.

Just for clarity your CPU contains an IGPU, which is not supported in macOS (Radeon RDNA 2 GPU), which you will need to disable when running macOS. You can do this in one of three ways:
  1. Disable in the Bios
  2. Disable by using a Boot Argument
  3. Disable using a custom SSDT.
The Dortania Ryzen OpenCore guide would provide all the necessary information you need to create a bootable EFI folder and installation media.
The only specific requirements for the A620/A520 boards from the main guide is you must provide are as follows:
  1. Add an SSDT-CPUR.aml or custom SSDT-PLUG-ALT.aml table for the necessary CPU fixes.
  2. Set 'SetupVirtualMap' Quirk to 'False/Disabled' in your config.plist.

As you have an AM5 system, you will probably need to look to see if your system requires ACPI patches and MmioWhitelist entries for your config.plist. These issues have been covered in a number of other threads.

ACPI patching - https://forum.amd-osx.com/threads/dsdt-patch.5391/post-44767

MmioWhitelist - https://dortania.github.io/OpenCore-Install-Guide/extras/kaslr-fix.html#using-devirtualisemmio

The other option is to run macOS as a Virtual Machine from Windows.
