I don’t know if this post fits here but the lineage os community has no traffic.
MIUI is bloated and limiting, so I decided to switch to lineageos, however, it doesn’t support my phone. Do I just wait, or is there anything I can do?
I also found this. Have no clue what it is, but maybe this can help. https://github.com/Jabiyeff/android_device_xiaomi_spes
There a bunch of custom roms for RN11. Crdroid and Pixel Experience have a good reputation.

Are they based on Lineageos?
Try crdroid, it has a degoogled option You can also look for a telegram group based on your phone name, there will be more roms there
