No, it's not easy. I just said, in the comment you replied to, "I'm not even sure that I have all the prerequisites on hand."

On my Mac model?
To be clear, I'm saying that the doc is wrong about my specific, relatively new Mac model, which I bought a year ago. I'm not claiming that the doc is wrong about other, older Mac models.
I have tested DFU restore on multiple Mac models including MacBook Air {M1, M2, M3, M4}, MacBook Pros {M1 Pro, M1 Max, M3 Max, M4, M4 Max}, Mac mini {M1, M4}, Mac Studio {M1 Max, M3 Ultra} off the top of my head (at least a bunch of older Intel+T2). I am sure many other people would have noticed if the DFU port was marked incorrectly. You are simply too quick to conclude what could be a bug in macOS updater is necessarily tied to DFU port designation. Just as an example, I have a USB-C flash device that is so flaky that sometimes does not work with a port on one direction and connect/disconnect and flipping the direction works. There's just any number of possibilities aside from DFU.
