I just hit a brick wall , need urgent help

I prepared a USB using OpenCore guide for Online Installation but unfortunately my wifi card and ethernet is not showing up in the macOS recovery, how can I overcome this obstacle ?

Do I need to download the complete macOS installer using gibMacOS ? If yes , then how would I be able to run createinstallmedia command since I don't own or have access to a Mac ?

My laptop specs:

Dell 3542

Processor : Intel Core i7 4510U

Built-in Graphics: Intel HD Graphics 4400

Dedicated Graphics: Nvidia 840M

Ethernet Controller : Realtek RTL810xE

Wifi Card : Qualcomm Atheros QCA9565 / AR9565
