You can install two different drivers for both cards. First of all, go to drive C:\. Find AMD folder, then open your RX 570 driver folder (depend on which driver type you are using). You will find a folder named "Package," save it to the safe place.
since you are using Blockchain driver the folder tree would be:
C:\AMD\Win10-64Bit-Crimson-ReLive-Beta-Blockchain-Workloads-Aug23\Packages
And then when I would try installing drivers through a disc which is the only way to force it to take some kind of drivers, which would then make the RX 570 show an error in device manager saying it doesnt have drivers and the same thing would then happen with the Rx 570.
That's the right move. Just need some other action to complete.
Open Device Manager, then find your RX 570, in Display Adapter section, and right click then updates manually. Find Packages\Drivers\Display\WT6A_INF\... in the folder that you save before. You will find inf file, then chose it. The system will be updating a driver for RX 570. If your 570 has been modded, don't forget to bypass driver signature using atikmdag patcher.
Restart your system....
