@jiny505,
Please try the following:
You should also create a custom USB port map by following this guide:
- Delete AMD9500Controller.kext from /Library/Extensions and run Kext Utility to rebuild the kernel cache.
- Install latest Lilu, WhateverGreen, and AppleALC into /Library/Extensions (if not already done).
- Then mount EFI partition of the macOS SSD, backup the existing CLOVER folder and copy the attached version in its place (rename the folder to CLOVER).
- Ensure that your display monitor is connected to the RX 580 and that nothing is connected to any video ports on the rear IO panel.
- In BIOS, set Initial Display Output to PCIe 1 Slot.
- Reboot and check "About this Mac" to see if the RX 580 is recognized.

I saw AMD Radeon Rx 580 is plug-in Windows10.
I installed new Catalina, and Library/Extensions are here
I installed Lilu and WhateverGreen and AppleALC with KextBeast to L/E.
And I copied your Clover to EFI/Clover and reboot.
But same problem. Graphics not working...
