We have to enable it in the GUI or set prop persist.sys.usb.config=mtp,adb either in build time or in runtime.

I have another option: Hack up adbd source in system/core Look at daemon/main.cpp, comment out line 161 and 163, force return true on line 93 https://github.com/LineageOS/android_system_core/blob/lineage-15.1/adb/daemon/main.cpp#L161 https://github.com/LineageOS/android_system_core/blob/lineage-15.1/adb/daemon/main.cpp#L93

The culprit is somehow PRODUCT_DEFAULT_PROPERTY_OVERRIDES doesn't override our adb props, or we don't know how it actually works

I built eng variant and set prop persist.sys.usb.config=mtp,adb in system.prop. My ADB can work with that.
