There isn't a canonical Dwelf option. In my experience that would be fairly uncommon, but it's nothing that hasn't been contemplated. Race is a tricky matter, even in D&D.

But you can make one. The Dungeon Master's Guide, starting on page 285, has guidance on factors to consider when creating new player races/subraces. It's got two worked examples, and you could also look at the player's companion from Adventurer's League's Elemental Evil campaign for other examples*.

*I'm not putting my hand on the supplement that gave us playable Goliaths and Svirfneblin--if anyone finds the link please feel free to edit that in, too.

You could also look at the player's companion from Adventurer's League's Elemental Evil campaign for other examples: Aarakocra (bird-people), Deep Gnomes (Svirfneblin), Genasi (half-elementals), and Goliaths (really big people).
