Works:

Pretty much everything that I wanted, don't really care about SD card reader.

Issues:

Brightness keys of keyboard don't work (DSDT patching didn't work, but please do recommend if any guide/ resource worked for you, including DSDT)

Missing System Fan RPM and CPU clock speeds in HWMonitor/HWMonitorSMC2 (they worked in my Clover High Sierra build)

For a working storage ecosystem, using one big partition~500GB as NTFS (using ntfs-3g/OSXFUSE)

Guides used: Primarily Dortania, occasional support from OpenCore configuration PDF, and few here and theres
