Editorialized title! Portrait aspect ratio (or "vertical video", as it's described here - at least I assume that's what the term refers to - like, as if the landscape aspect ratio has no Y axis!) is not obviously mentioned anywhere.
I don't get why the poster thinks NewPipe doesn't support vertical videos (let's not be anal, we know what they mean) if the video is "vertical" then making it fullscreen will fill the phone's screen vertically.
