The Shimano Deore XT FH-M8110-B is a high-quality rear MTB hub designed for 12-speed Microspline cassettes. It has 28 spoke holes and a thru-axle attachment style. The hub has a Boost 12x148mm spacing.  Centerlock rotor attachment allows the use of Shimano's best rotors, or use other brand 6-bolt rotors with an adapter (not included).  This was purchased for a build that didn't end up happening, my loss is your gain.
