Check out Vulkan Ray Tracing Position Fetch Extension which introduces VK_KHR_ray_tracing_position_fetch extension which exposes the ability to fetch vertex positions from an acceleration structure hit when tracing rays.
This would replace existing uniform buffer ObjDesc which contains vertex and index addresses and unnecessary descriptor bindings in the ray tracing pipeline.
