How to interpret a serialized acceleration structure

For a different project I’m interested in using an acceleration structure but was hoping to not have to build one myself. Having worked with vulkan before I found that VkCopyAccelerationStructureToMemoryInfoKHR(3) was a thing. However, it is not specified what the data will contain.

I think one problem could be that it is never specified that a BVH is used and that is up to the vendor. Does anyone have any experience with reading this data? (even if it is nvidia specific)
