You can directly install Mojave without modifying anything in the bios... using this EFI..
But if you have to install/upgrade to Catalina 10.15.2, before installing or upgrading
Disable
Virtualization support - CPU configuration
disable VTX-D - North bridge.
Disable USB ECHI support
Post installation you can enable them again. Had no issues with virtualization performance etc...
Boots in less than 10 seconds.
All working - except small static in AUDIO... (hardly noticeable, but goes away once you play something)...
