OpenWrt Packages For 5G modems Missing

I would like to ask if someone can add these packages /or should be available on official OpenWrt / Snapshot Where i'm using Banana BPI-R4

https://firmware-selector.openwrt.org/?version=SNAPSHOT&target=mediatek%2Ffilogic&id=bananapi_bpi-r4

These packages :
AT commands & Modem LTE/5G manager

The OpenWrt looks like missing a lot of important packages for 5G modems M.2 where its available on fork or developed by people on OpenWrt 21.0

I appreciate if you can guide me how to install these packages on OpenWrt
