No, as of now only switching off proxy_next_upstream completely is
available.

On the other hand, with switched of proxy_next_upstream you may
still configure retries to additional (or other) upstream servers
via error_page directive, using a configuration similar to last
example at http://nginx.org/r/error_page.

Something like this should generate no more than two requests
regardless of number of upstream servers configured:

location / {
error_page 502 504 = @fallback;
proxy_pass http://backend;
proxy_next_upstream off;
}

location @fallback {
proxy_pass http://backend;
proxy_next_upstream off;
}
