ThinkPad T440 (non-S) Catalina/Big Sur

I just got my T440 in. Specs: i5-4300u, 8gb ram (dimm only, no soldered ram), 1080p panel (must be an aftermarket, no 1080p from factory), and stock synaptics touchpad. I want to run either Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina or Big Sur on it. I've searched and searched. All I've found were Sierra guides, and they were for the T440s, not the T440.

Is there a guide to follow specifically for the T440, or is it the basic OpenCore guide? I know wifi is kinda broken, or at least varied (with the stock wifi card), so I plan on using 3rd party card or wifi dongle.
