It was common to have a headlight levelling dial for a period, I'd say from the 2000s up to mid-late 2010s. Prior to that most cars only had mechanical adjustments, post that most cars have auto levelling headlights - over a certain brightness this is legally required.

You might find a setting for headlight levelling buried in some car settings still but I don't recall a physical dial for this in cars I've driven from the last 5 years or more.

Note that this might be a country specific thing, particularly re. requirements for auto levelling (this is true in Australia at least).
