First thing I would recommend is for you to update the version of Clover you are using. You are using a fairly old version v2.4k r4722. I would recommend you update to Clover_r5119, copy attached below. r5119 was one of the last versions that didn't include any OpenCore entries, which tend to mess the bootloader up, the newer versions tend to result in unexpected kernel panics.

I will have a look at your EFI folder and get back to you shortly.

Here is a revised CLOVER folder for you to use. It has been tweaked to better reflect your system.

See how this works graphics wise, as I have changed the Device Properties for the IGPU and added the RadeonDeInit=true options for your RX 570 dGPU.
