Form submission without a `text/vnd.turbo-stream.html` Accept header?

Is there a way to get Turbo to submit a form without adding a text/vnd.turbo-stream.html Accept header? I’d like the redirect to result in a regular html response so that Turbo Drive performs a full page update instead of a Turbo Stream response (which is already used for infinite scroll pagination on the action redirected to).

Adding an event handler to the form turned out to be one way to do it:

form.addEventListener('turbo:before-fetch-request', (event) => {
  event.detail.fetchOptions.headers['Accept'] = 'text/html, application/xhtml+xml'
})

Why not just turn off Turbo for the form?

<form action="/messages" method="post" data-turbo="false">
  ...
</form>
