Device information
Some device information that may or may not be useful for further development

Based on the previous command output and PostmarketOS kernel .config file, it seems that this device supports some version of SATA, PCI and also routes audio on bare ALSA.

Installation
Create a recovery.zip and flash it with TWRP. Make sure that in TWRP you unmounted the partition you want to flash on by default that would be "SYSTEM".
