It was shortly discussed in this other thread and the answer is not unless a developer hacks the Lidl/Tuya gateway and also creates a third-party firmware for the Lidl/Tuya gateway that which in turn could, for example, run a serial TCP server, etc. to then be able to remotely share and access UART to Zigbee coordinator SoC:
It would be a lot of work bit it is not impossible for a developer to code such third-party firmware for it.
However instead of posting about that there I suggest that you create a new thread to solely discuss “hacking the Tuya Zigbee gateway / Lidl Zigbee gateway with third-party firmware” as that is really a whole separate discussion.
OpenLumi is doing something similar with an OpenWRT fork the Xiaomi/Aquara Zigbee bridge:
Zigbee2Tasmota (Tasmota sub-project) done something similar with Sonoff ZBBridge Zigbee bridge
https://tasmota.github.io/docs/Zigbee/
Both those specific projects are however for different chip than what is in that Tuya / Lidl gateway.
Regardless I think third-party firmware discussion for the Lidl/Tuya gateway is off-topic for this thread.
