It’s very likely using the same Silabs EFR32MG21 SoC and signed EmberZNet Zigbee NCP firmware as the original Sonoff ZBBridge ZB-GW03 (Eachen eWeLink ZbBridge Pro Ethernet Zigbee Gateway).
If so then yes Home Assistant’s ZHA integration and Zigbee2MQTT could use it if could get direct serial access to that Silicon Labs EFR32MG21 SoC and it was flashed with compatible firmware. See ex.:
ZB-GW03 eWeLink Ethernet Zigbee Gateway is a spiritual successor of the ITead Sonoff ZBBridge
It features an ESP32 chip and a wired Ethernet port (instead of the older ESP8266/ESP8285 and WiFi).
The Silicon Labs EFR32MG21 based Zigbee SiP radio module it uses is the exact same “SM-011 V1.0” modules and Zigbee firmware by CoolKit-Technologies that ITead Sonoff ZBBridge board uses.
The good news it that Tasmota community member cronyx has now hacked it with Tasmota ZBBridge firmware (using same…
Itead has just launched Sonoff ZBBridge which is an inexpensive Sonoff Zigbee Bridge which is based on a similar design as their Sonoff RF Bridge

According to the teardown and notes on notenoughtech.com and cnx-software.com it sounds as if it is based on Silicon Labs EFR32MG21 (EFR32 Mighty Gecko) for Zigbee 3.0 radio module support and ESP8266 (ESP8266EX) for WiFi and bridge/gateway/controller software
By default it uses the eWelink cloud but hop…
If you've been using your Zigbee bridge with the ZHA integration and don't like some of the oddities of buttons using ZHA Events, etc or simply just want to detach from HA, or even enable support more devices; it's time to jump on over to...
