To mine, you need the blockchain driver. And the blockchain driver won't support the much newer 2400G (basic MS driver will be used for iGPU). Now if you install the proper 2400G driver, it will also be used your dGPU, which means poor blockchain performance. And if you will try to install the blockchain driver AFTER the 2400G driver, you'll get a violent crash, bluescreen and Pennywise the Clown in your closet.
The only option I see here is to hope for AMD to update the blockchain driver or include the blockchain computation mode in regular drivers, which they aren't doing.
So, well, we're kinda hooped. By my thoughts and prayers are with you, young Padawan.
