Very unlikely. The Zorro.mq4 file looks nothing like this:
https://github.com/darwinex/Darwine....1/MQL4/DWX_ZeroMQ_Server_v2.0.1_RC8.mq4

You would need ZMQ on both endpoints (i.e. a complete DLL library both Zorro-side and MT4/5-side), and I do not see it on either endpoint.

More likely the MT4/Zorro bridge is directly using the Windows API IPC capabilities.
