The reason the chip fails for fire-based people is that they are setting their actual molecules on fire. In the case of, say, Toro, he is fire when he is on fire. His lowest point of heat is 780 F, but can climb up to the heat-pulse of a nuclear warhead detonation. So, not a lot can survive that kind of heat/energy expenditure. I think that it would be possible for her to overwhelm or short out the chip, but it would take a great deal of energy. I might say that it would be possible during an attack, rather than something she could do on her own? Either way, yes, it is possible---but difficult.
