From the screenshot you provided at the start of the thread, this is not GPU related. But there has been no evidence showing any specific manufacturer of any RX series GPU not working. It has all been misconfiguration of the user. Upload your entire EFI folder and if you have used MultiBeast to install 3rd party Kext move those into the EFI/Clover/Kexts/other folder before upload.
XFX RX 590 has a custom vbios. I tested one alongside the Powercolor model. Powercolor works it logged right in but XFX was a no go. Someone flashed their Fat Boy with Sapphire Niro bios and it worked.
