Does varnish support unix socket files?

I'd like to accelerate my website by adding a varnish reverse proxy (HTTP accelerator/cache) before my web server. My web server's virtual host is currently configured to listen for connections on a "UNIX-domain socket". For more info on this config, see the "path" argument for the "listen" directive in NGINX:

Is it possible for varnish to communicate to my existing nginx server's config over a unix domain socket file as its backend?

And is it possible for varnish to also itself listen on a domain socket?

linux nginx varnish socket posix

    Varnish has had support for Unix Domain Sockets (UDS) for both clients and backend servers since Varnish 6.0 was released in March 2018.

    You can define a backend to use a UDS using the .path field in the backend declaration. Or by using the -b argument in varnishd.

    Varnish itself can listen on a UDS using the -a argument when starting varnishd
