Gaining and losing the mammalian dive reflex

So through training and specific techniques I know that the dive reflex can be made to come on earlier, benefit a dive and more. But is it possible that you can also lose the mammalian dive reflex over time?

I don't think you are gonna loose your mammalian dive reflex, they are part of you as mammals, maybe it's gonna be a bit weaker at the beginning but i noticed even after few months break of diving, it comes back so quickly ;)
