asciidoctor: How UNSET boolean attribute via document header

In asciidoctor I can overwrite any attribute value given on the CLI via a document header value, when I append '@' to the value on the CLI.
Example: -a icontype=png@ is overwritten by :icontype: svg in the doc header. Good.

Problem: Boolean attributes.
How would I UNSET a boolean attribute given on the CLI, like -a data-uri.
Use Case: My .adoc renderer should by default set data-uri, but I would like to switch it off sometimes via a document header attribute.

Is that possible?
