I could wrap this scheduler and provide additional values to the step method, but as of diffusers 0.24.0, the scheduler has been deprecated: https://github.com/huggingface/diffusers/blob/v0.24.0/src/diffusers/schedulers/deprecated/scheduling_karras_ve.py#L164

I'm not going to add new patches to support deprecated schedulers/pipelines unless they offer something that the replacement does not, but I don't think that is the case here.
