I'd suggest going the OpenCore route. Use this EFi folder on your USB Boot drive, it already has the agdpmod=pikera boot argument but lacks kexts for a DW1560 but those can be added.
If you feel like you have to stay with Clover maybe this EFI will work for you.
#3,816 It did for
@perics
Ha-zah! Thanks the EFI from post
#3,816 worked! Its crazy after struggling with this for days, once I had the right sauce Catalina booted in like 5 seconds!
Very big thanks to
@ModMike for the guide,
@Leesureone for his continued troubleshooting help, and
@iDrakus for sharing his EFI!
Posting my build for anyone else:
Motherboard: Asus z390-I Strix Gaming
CPU: Intel i7-9700k
GPU:
Sapphire 5700 XT Nitro +
HDD: Western Digital WD BLACK SN750 NVMe
WIFI/Bluetooth card:
BCM94360NG
Issues encountered:
1. After Catalina install, could not boot into Catalina, system hang/reboot loop at 50% loading screen
- Resolution: Instead of ModMike's EFI on page 1, used the EFI folder iDrakus shared from post
#3,816 , replace the EFI folder (in the hidden EFI partition) on your install USB with iDrakus's EFI folder. Then do the same replacement for the EFI folder (in the hidden EFI partition) on the Catalina harddrive installation.
2. Could not load Catalina setup/install, system hang/blank screen at 50% loading

Resolution: Using Clover Configurator, Add the "agdpmod=pikera" boot argument to the config.plist
*NOTE* Using the EFI folder from #1 resolution above will solve this issue as well (the EFI already has the boot argument added) - So this resolution step is not needed if you have already completed the above.
Thanks again!
