"Until recently, the vicuña was thought to not have been domesticated, and the llama and the alpaca were both regarded as descendants of the closely related guanaco. But recent DNA research has shown the alpaca may well have vicuña parentage.Today, the vicuña is mainly wild, but the
local people still perform special rituals with these creatures, including a fertility rite."

There is a farm that sells Paco-vicuna which might be a alpaca:

Since Vicuna was an endangered species:
Both under the rule of the Inca and today, vicuñas have been protected by law, but they were heavily hunted in the intervening period. At the time they were declared endangered in 1974, only about 6,000 animals were left. Today, the vicuña population has recovered to about 350,000,[1] and although conservation organizations have reduced its level of threat classification, they still call for active conservation programs to protect populations from poaching, habitat loss, and other threats.
Can you get a Vicuna to raise?
