How to dynamically show or hide meshes from a Burstable ForEach job using Hybrid Renderer V2 in unit

    I have a specific way of generating meshes and structuring my scene that makes occlusion culling very straight forward and optimal. Now all I need is to know how to actually show or hide a mesh efficiently using the ECS hybrid renderer. I considered changing the layer to a hidden layer in the RenderMesh component but the RenderMesh component is an ISharedComponentData and so does not support jobification or burst. I saw the Unity BatchRendererGroup API and it looked promising with its OnPerformCulling callback but I don't know if it is possible to hook into the HybridRenderSystem's internal BatchRenderGroup. I also saw the DisableRendering IComponentData tag that I guess disables an entities rendering. However, again, this can only be done from the main thread. I can write my own solution to render meshes using Graphics.DrawMesh or something like it, but I would prefer to integrate it natively with HybridRenderer in order to also cull meshes that are not related to my procedural meshes.

    Is any of this possible? What is the intended use?
