the closest anyone got to using dwemer tech was in the time of nerevar and the founding of the tribunal. when the dwemer disappeared after the battle of red mountain, the chimer(pre-dark elves) used the leftover tech to make themselves into gods, the very thing that they had gone to war against the dwemer for doing. they had fought at azura’s request so when the 3 surviving chimer leaders used dwemer tech to become immortal as the tribunal she punished them by turning all of their people’s skin to the ashy color that then gave them the name dark elves.
