I tamed it by luring it into a premade trap with 3 billboards, 1 foundation and 2 walls/doorways for the 2 ceilings on top, and a bear trap deep in the trap.

Once it’s trapped, place the 4th billboard as close as you can, so it doesn’t have any gaps in the ceiling.

It may take a few tries and helps to have the area cleared out so it stays aggroed on you, but it was super easy once I prebuilt the trap and walked it in.
