Hello in the round,
this has been discussed many times, but as far as I know, there is no sound evidence.
Not even whether it is a real calm at konjac, where the shoot is inhibited by whatever.
In many plants, abcanic acid plays a role, which inhibits the shoot of vegetative buds and which must be broken down in order for the bud to expel.
Various factors can work, such as temperature (cold (vernalization), heat, day length, ethylene, etc.)
I don't know what matters at konjac.
I haven't found any literature about it either.
The effect of a 1-month exposure of the tubers of Amorphophallus muelleri was investigated here:
https://rjls.ub.ac.id/index.php/rjls/article/view/142The article can be downloaded as pdf....
The conclusion seems to be that exposure of the tubers promotes the shoot.
For konjac, I would then summarize that the tubers should be stored bright and warm in order to achieve the early shoot possible.
In order to further investigate the influence of gibberillinic acid and ethylene (see bottom left), further experiments would have to be made.

A. yuloensis is still asleep
Strange that you can't find any more or reliable information about this....
Unhappy, Bernhard.
