Command option to set location accuracy (was: Is Network location based on UnifiedNLP?)

I'm using microG for LineageOS 21 on Redmi K40 (alioth) device. I have configured UnifiedNLP with several backends, which should work fine (I installed https://f-droid.org/packages/com.mirfatif.mylocation/ and it correctly displayed my coordinates from both GPS and NLP backends, on several locations).

However, I found that FMD cannot locate myself when I'm in-door, where com.mirfatif.mylocation only have UnifiedNLP location working properly. I didn't use OpenCelliD. So that makes me wonder if FMD does not use UnifiedNLP?

Thank you very much!
