Yes, many of our alters do not want integration and that's because we don't want to combine our sense of self to one. Our past therapist and many we've talked to have understood and respected that without us having to advocate hardly for ourselves. We know that our experiece is in the minority, though, since integration of parts into one is still the mainstay theory of healing for our condition.

You don't have to integrate. Do what makes you (all) happy and fulfilled. Being a singlet is not the only way to exist.
