This means you have iMac19,1 (because Sidecar is working). I will try this SMBIOS later tonight.

Yep iMac19,1
The only problem I had was getting the "Drive Ejected" error during sleep, but I think this was because I'd changed my DRAM speeds back to above 2666 - so whoever thought the Catalina upgrade had fixed this - it hasn't

Does disabling CNVI in the new BIOS remove the need for the CNVW SSDT? Does it disable the onboard bluetooth as well?

Good question: It should disable Bluetooth as well but I did not specifically check that. Maybe yet another addition to my To-Do list.

But the CNVW SSDT should be removed when disabling onboard WiFi -- keeping it in place will not cause any harm, but it will log an ACPI error during boot (which can be ignored).
 
I just installed the 2019-001 Security Update for Mojave 10.14.6. No problems.

Just out of curiosity, how quickly should your system boot? Does 30 seconds sound about right for an i9-9900k with a 970 Pro (2400MB/s read + 2800MB/s write)? (That's timed from the disappearance of the Clover menu to the MacOS user list for logins.)

All who are involved with testing different memory fix drivers and such, have you guys messed with above 4g decoding? I just realized that setting is enabled in my UEFI firmware (I can't remember why I enabled it, but it is enabled, I know by default it is disabled). Another thing I just realized about my UEFI config, I disabled the second ethernet adapter (the i211), mainly because I'm not use it at this location, the i219 is good enough for what I need...

I'm only mentioning these because they may perhaps play a role in getting all this working? Perhaps disabling certain features may allow more memory to be freed for the macOS kernel space, resulting in successful boots each time.

I just now tested booting using f12 menu, booting directly into Windows (7 and 10), macOS still working. IGPU has been enabled, CSM was disabled (will try later with it enabled), no WIFI card installed, still on F7 BIOS (will update to F8 some time later today). But as mentioned above, above 4g is enabled, and the second ethernet adapter disabled. Maybe we all have to find some sort of tradeoffs in enabling/disabling certain things to make enough room for kernel space? I mainly got this board because it was at a good price, less than what I would pay for a Z390 Aorus Pro and a separate TB3 card lol.

I don't remember an option in BIOS to selectively disable a single NIC. Is it in F7? I can't check right now but I don't think F6 offers that.

30 seconds is a bit too long -- but only a bit. If verbose boot mode is disabled (no flurry of log messages filling up the screen during boot) then a typical boot time between Clover and Login screen with NVMe SSD should be around 15-20 seconds. Adding the boot argument -disablegfxfirmware can speed up boot times under certain circumstances.

Not sure about F7, but in F8 the option is located here:

Re:10.15.1
If you update, be sure to update WEG first!
If you don’t...you’ll be sorry.
