Yes, the behavior happens for a reason, so focus on addressing that reason with your response to it. Coming down solely on the behavior does not do this. Recognizing WHY he is biting when he bites, and conveying understanding for the feelings that are driving the behavior, is important. You said it happens when he doesn't get his way. So it's a matter of not knowing what else TO do when he's feeling frustrated, angry, disappointed, powerless, outraged... Those kinds of feelings involved in grieving a loss (finding that you weren't able to make things go your way) are hard for older humans to manage, let alone someone who is almost 3. This is the guidance you offer.
When at all possible, be preemptive or proactive & prevent the behavior from happening. At the same time, focus on showing empathy, not disapproval. Convey understanding for why he bit (or if you managed to prevent, show empathy for how he's feeling) & encourage him
