It probably does. But only if something happens or if they have utter control over their Titan form, like how Reiner was able to channel his consciousness or halt the regeneration, or how Annie was able to summon Titans or channel energy. Since most of the Reiss family didn't as they were bound to the first Kings will they probably weren't able to do it.
