Rom with Volte support?

Welcome!
What custom rom support Volte by default? How to check Volte support?
which rom support Volte?
I tried also a lot of custom roms including the old official and unoficial LOS, unoficial LOS 15.1., 16, Nexus OS etc. and VoLTE / WifiCalling was not supported by any of the rom. I am also verry interresting in possibility to use VoLTE/Wifi-Calling in any custom Rom. For now I probably will go back to stock because there its supported.

How to compile AOSP for Xiaomi 9a

Hi, I have a Xiaomi redmi 9A and I'd like to compile and flash a custom android os, preferably AOSP or LineageOS.
What I know so far is that I need
1. Rom's source: I can simply get AOSP or LineageOS from their repository
2. Kernel files: xiaomi released the source code here.
3. vendor files: I can extract it from stock roms as explained here.
4. device files
The only bottle-neck for my phone is device files. where can I get them? can I extract them from stock rom? or from a rooted device? looks like mediatek (which redmi 9a uses) is not open-sourcing them. Is there a chance to get them?
