Can you get free games on VR?

I'm curious, can you actually obtain free games on Virtual Reality (VR) platforms? It seems like the world of VR gaming is booming, and with so many exciting titles available, I'm wondering if there's a way to enjoy some of these experiences without breaking the bank. Do developers or platform providers offer any sort of free trials, giveaways, or other means of accessing VR games without having to purchase them outright? And if so, how do you go about finding and accessing these free VR games?
