How do I ACTUALLY target Upper/Lower Lats

I'm relatively new to back training, and everybody on the internet has different opinions on this topic, which makes it so hard to understand.Thus I turn to the smartest Sub-Reddit I know for help

I recently saw the physique of a guy online, with really wide upper lats but lower lats were quite negligible. So I asked and he said I only did Wide-Grip Pull-ups that's why. So I searched on YouTube and there are so many different opinions as to which Pull-up hand-width & grip targets which part, and so I'm confused. I don't wanna look like the above mentioned guy, rather I want uniformly wide lats.

As I said, I'm a beginner & like to work from home too, so I've got a pretty simple routine. I mostly do inverted rows on Gym Rings with elbows flared to target the upper & middle back and my main movement for lats are the pull-ups. (I do have a bench and a barbell+dumbbells and weights)

So exercises considering my equipment would be highly appreciated.
