Carrot left the mines at 16, when he couldn’t grow much of a beard. His early days on the watch with Colin the Traditionalist would have required being clean shaven. By the time Cuddy joined Carrot likely was set and comfortable being clean shaven. As to why he continues to shave, you’d have to ask him (or possibly Angua)
However! That doesn’t make him D’rzka any more than being human by birth would. He can properly ha’lk his g’rakha, and is, in every way that matters, a dwarf.
[Female dwarves are] in voice and appearance, and in garb if they must go on a journey, so like to the dwarf-men that the eyes and ears of other peoples cannot tell them apart.
(Yes yes, JRRT waffled on this. But come on! This is good lore, let’s keep it)
The real issue is not the existence of darker skinned dwarves.
The issue is beardless dwarves.
There is no canon reason why Tolkien’s dwarves couldn’t all be bearded like Pratchett’s dwarfs, and thus it must be.

Does Carrot have a beard though?
Him being adopted doesn’t mean he isn’t an exemplary dwarf.

Tolkien went back and forth on this, as he did with many things
