Unable to use X-Http-Method-Override header with Lambda Function URL


When trying to invoke a Lambda function through its function URL issuing a POST request with "X-Http-Method-Override" header set, the response is always HTTP 403 Forbidden with body:

  <Message>Unable to determine service/operation name to be authorized</Message>

Is there anything I can do to use this header to change the HTTP method? Alternatively, can I pass it to the function?
