How to selectively remove checking for a particular element-required-attributes rule?

I am using a MarkDown processor (GoldMark) that does not include a "scope" attribute in <th> elements.

Yet the standard rule set includes that as a required attribute.

I want to disable just this rule (yet retain the general element-required-attribute rule for other elements).

From the docs, I was only able to glean I could add a rule to my .htmlvalidate.json.

"element-required-attribute": "warn"

as a work-around. Is there a more specific way to exclude just that element from the ruleset?

Use cases

Perhaps a rule syntax that allows for more granualar editing:

"element-required-attribute": {
  "th": {
    "scope": "off"
   }
}
