Dependent origination explains the fire. (made out of the 5 aggregates) It explains how this fire burns because of oxygen, fuel, etc. how it produces light, heat etc. It explains the conditionalities between fuel, heat, light, oxygen etc.
Nibbana is when this fire (described by DO) does not exist anymore because no more fuel (craving) has been put in and, lacking fuel, the fire has been extinguished.
The "fixed course" of dhammas pertaining to Nibbana, although not directly mentioned in the suttas, is the absence of greed, hatred & delusion. The sadhatu or sabhava of Nibbana is always the absence of greed, hatred & delusion.
When there is no more fire (no more aggregates subject to clinging) there can not be any craving because the things that could be subject to craving do not exist anymore. Saying nibbana is the absence of hatred and delusion is incorrect. That means you believe in a state of been or even, god forbid, a self not subject to greed, hatred & delusion. The only way to describe nibbana is by using the fire metaphor. One who understands things this way would not describe nibbana as absence of hatred or delusion because it is the absence of everything. One could very well say nibbana is the absence of compassion, absence of wisdom, absence of mindfulness etc. or pick any things that exist and say nibbana is their absence. Nibbana is the absence of all conditioned things, meaning everything. Greed, hatred, delusion, compassion, generosity, etc. are all part of the fire. Nibbana is when this fire gets extinguished.
Bhikkhus, there are these five faculties. What five? The faculty of faith, the faculty of energy, the faculty of mindfulness, the faculty of concentration, the faculty of wisdom. These are the five faculties.
When, bhikkhus, a noble disciple understands as they really are the gratification, the danger, and the escape in the case of these five faculties, then he is called a noble disciple who is a stream-enterer, no longer bound to the nether world, fixed in destiny, with enlightenment as his destination. ”
