Finiteness conjecture for low-volume hyperbolic knot complements with hidden symmetries

A hyperbolic knot complement is the complement of a knot in $S^3$ admitting a complete finite-volume hyperbolic structure, and its volume is denoted by $\operatorname{vol} M$. A knot complement has hidden symmetries when it non-normally covers another hyperbolic $3$-manifold.

Finiteness conjecture. For any $R>0$, at most finitely many hyperbolic knot complements have hidden symmetries and volume less than $R$.

The conjecture is motivated by results producing infinite families of non-accidental-parabolic hyperbolic knot complements without hidden symmetries, while hidden symmetries are known to be rare among knot complements. Its resolution is not stated in the supplied source.
