How to start with GenieACS and TR069 (Huawei ONT provisioning))

Hi everyone.
I have a GenieACS server on Centos7 (cwmp+nbi+fs+gui).
Server is working on MongoDB 4.4.0

I need to have some basic information how to start adding some data to ACS to provision services on Huawei ONT.
Basically ONT is added to OLT with some line/service profiles, also service-ports are created but i don’t know how to add rest of data to ACS Server - data which can not be added via SSH

Maybe someone have some experience with this.

I know exactly what i need to do on OLT site (tr069-server-profile, ont tr069-server-config, etc) but the problem is what should i do and how to put some specific data to ACS database, for example how to add do ACS server specific SSID, password, channel, etc to specific serial numer of Huawei ONT

Thanks for any help
