If I'm not mistaken, you only need to enable the RadeonDeInit option in the config.plist file. I use Clover Configurator to modify my config file and that option is under the Graphics section. If this option does not get the card working then you will need to use Whatevergreen and Lilu kext by placing them in the /EFI/Clover/kexts/Other folder.

Once the card is functioning correctly then you should disable the onboard GPU.

As I understand, High Sierra, even the earlier version of Mac OS drop the support of VGA output. I don't know what type of RX570 you got still have that dino technology.
