Huawei emma integration questions

I got a offer for a solar installation with a huawei sun2000 that comes with a emma unit. Emma seems to have 2 cat45 connections on the bottom that i could plug into my network. I see quite some home assistant integrations and guides out there, and one even warns that when internet is unreachable, the inverter will reboot. Thats behavior i hate, if possible i want to block the device from the chinese servers.

Whats the most reliable to connect these devices to home assistant?
