Currently, Spine's core runtime is not structured in a way that easily allows for integration with Unity's DOTS (Data-Oriented Technology Stack), which includes the job system and burst compiler. The Spine runtime would require a significant rewrite to be compatible with DOTS, as it would need to be restructured to use plain structs, which is not feasible in the near future. There was a third-party asset that provided basic Spine functionality for ECS and Tiny, but it has been discontinued. You might consider reaching out to the original seller if you're interested in exploring that option further.
