No, currently proxy_cache does not allow directio. I can say right now
the reason why, but you may try to control it by changing in
src/http/ngx_http_file_cache.c

    of.min_uses = clcf->open_file_cache_min_uses;
    of.events = clcf->open_file_cache_events;
-   of.directio = NGX_OPEN_FILE_DIRECTIO_OFF;
+   of.directio = clcf->directio;

    if (ngx_open_cached_file(clcf->open_file_cache, &c->file.name, &of, r->pool)
