Bring ghillie and stay behind it the best you can. If you have scorched earth, you can also make cactus soup, which also reduces agro range on wild animals. Beer takes 6 hours per beer, so plan ahead, and I suggest making multiple kegs, the more the marrier.
For beginners these things will spot you in a split of a second so don’t even think of going up to it with a stimberry in your hot bar. Instead, get a ghille suit and sneak behind it and feed it a beer! Don’t use stimberries it is pain And time consuming unless you have a bush of stimberries. They eat berries after they are tamed though. Not beer.
To tame this creature you have to passively tame it, the best way of doing this is to put on a full set of ghillie as that supply's stealth, then you Aproach it from behind crouching and Feed it a beer!
