The antonyms for the phrase "more interrelated" could be "less connected," "disconnected," or "unrelated." These words imply a lack of association or correlation between different elements, unlike the interconnectedness and interdependence suggested by the original term. Some other potential antonyms could include "independent," "isolated," "separate," or "distinct," which all emphasize the autonomy or distinctiveness of individual parts rather than their interrelationship. However, it's important to note that the opposites of "more interrelated" may not necessarily be negative qualities; in certain contexts, a degree of independence or disconnection may be desirable or advantageous.
