the o.p said his drum uses lugs, not ropes. he's not going to be able to pull diamonds.
you could try tightening the lugs, a bit at a time. always tune on opposite ends, going around until all lugs have been tuned equally. keep going until the overtone is reduced. you may find that some overtones still remain, due to the fiberglass shell, its smooth interior, and the metal tuning lugs. rope tuned tocas fair better, at least the ones i've heard.
