Can ID column be displayed when configuring a list form header using JSON?

I would like to display the ID of a list item on a JSON-formatted form. I tried adding “ID” directly but it would not render. I created a calculated column that is the concatenation of ID and Title. This field renders fine in the BODY but not in the HEADER.

How can the ID of a list item be displayed in it’s JSON formatted header?

Or, is there some workaround/hack that can achieve this same functionality?
