This is not currently posssible.

On the other hand, if you want to make the page more useful in 
your particular use case, you can do so by configuring appropriate 
page with the error_page directive, see here:

http://nginx.org/en/docs/http/ngx_http_ssl_module.html#errors

Certificate verification results can be found in the 
$ssl_client_verify variable.
