Minimal noncommutative desingularization conjecture for canonical singularities

Let XX have canonical singularities, and let q:YXq:Y\to X be a finite morphism with YY smooth. The pair

(idX,End(qOY))(\operatorname{id}_X,\mathcal{E}nd(q_*\mathcal{O}_Y))

is a noncommutative desingularization of XX.

Minimal noncommutative desingularization conjecture. The pair (idX,End(qOY))(\operatorname{id}_X,\mathcal{E}nd(q_*\mathcal{O}_Y)) is a minimal desingularization of XX.

The claim proposes a canonical minimal desingularization in the noncommutative interpretation of the minimal model program. The source does not provide evidence resolving it.
