1. Copied my already installed graphics related kext files of IntelGraphicsFixup.kext, NvidiaGraphicsFixup.kext, and Lilu.kext to EFI/EFI/CLOVER/kexts/Other in an attempt to avoid pulling my Nvidia card as I did for the initial 10.13.2 update. I figured since adding FakeSMC.kext there was needed for my setup during the last update, then maybe it could fix future graphics card issues during updates.
2. Did a time machine backup. Mounted the EFI and made a zipped copy of its contents. I learned from the last update that with the usb boot drive, this was all I needed to fully recover my APFS system drive.
3. Updated via the App Store.
4. Crossed fingers.
All went well. Confirmed system version 17C205 and Safari 11.0.2. Dual monitors setup and sound is all good. I don't use the Nvidia web drivers because the OS appears to drive my GT 710 just fine without it.
Geekbench single-core score of 4896 and multi-core of 14304 which is nearly exactly as before the update.
I don't know whether step 1 helped for this update or whether my logic is all good there, but apparently it did not hurt.
