Is it possible to determine if an entity or device is disabled in Jinja2?

Configuration
1

Is there some built-in function that will determine if an entity or device is disabled that can be used within Jinja?

2

Alternatively, it looks like core.entity_registry indicates when an entity has been disabled, is there any way to get that JSON into a template or Jinja2 object for examination?
