Can I use ss and filter on PID and FD?

I'd like to be able to run ss and filter on PID=$(pgrep emacs) and FDs=(5u|6u|8u). Does ss support filtering on either (or both) of these? Or is the best option to compose with grep? I'm currently using lsof, but I'd prefer to use ss:

lsof -p $(pgrep emacs) | rg '\b(5|6|8)u\b'
