I found a workaround, which is to instead set the visibility of the pivot in the custom model instead.

models.model.root.Body.ChestplatePivot:setVisible(false)

However, if you disable all the custom pivots of an armor piece, it becomes visible again, and no longer respects the transformations done on those pivots. So as a rule of thumbs, the correct way to toggle any armor mesh is to always disable/enable both the vanilla and the custom one:

models.model.root.Body.ChestplatePivot:setVisible(XXX)
vanilla_model.CHESTPLATE_BODY:setVisible(XXX)
