Custom aria-describedby property in hmpoRadios component

[GDainton]

The current hmpoRadios version always uses the fieldset hint property when rendering the aria-describedby html tag, which is used by accessibility screen readers to describe the fieldset in question. If the hint property is removed in the code like so:

{{ hmpoRadios(ctx, {
id: "couldNotMatchChoice",
namePrefix: "couldNotMatchChoice",
fieldset: {
legend: {
html: "<h2 class="govuk-!-margin-bottom-0">What would you like to do?",
isPageHeading: false,
classes: "govuk-fieldset__legend--m"
}
}
}) }}

then the aria-described still populates with value couldNotMatchChoice-hint. This means that nothing is read out, but there is no way to use other values as is a current requirement in a BAV CRI screen. Can this component be updated to accept other values or no values at all for the aria-describedby element in the HTML?
