Disable TRACE an OPTIONS in NGINX-ingress with snippets

A security probe recently recommended disabling the TRACE and OPTIONS methods for my K8s nginx-ingress. I’ve been googling for a few days but not gotten anywhere, the searches are a bit vague. I think for the TRACE option I have:

        server-snippets: |
          opentracing off;

But this is a bit of guessing, and I haven’t found anything concrete. Also, is there a way to turn off the OS/Fingerprinting options in the same or similar blocks for consistency?
