How to modify default "_headers" values?

[stefanobartoletti]

I'd like to modify and override some default values printend in the _headers file, but I can't find how.

To be more specific, I want to set the strict-origin-when-cross-origin as the value for Referrer-Policy, while the default configuration has origin.

I tried by passing this option object into nuxt.config.js

{
  netlify: { 
    headers: {
      '/*': [
        'Referrer-Policy: strict-origin-when-cross-origin',
      ],
    }
  }
}

but as a result, the _headers file contains two entries for Referrer-Policy, as follows:

## Created with https://github.com/juliomrqz/nuxt-netlify
/*
  Referrer-Policy: strict-origin-when-cross-origin
  Referrer-Policy: origin
  X-Content-Type-Options: nosniff
  X-Frame-Options: DENY
  X-XSS-Protection: 1; mode=block

/_nuxt/*
  Cache-Control: public, max-age=31536000, immutable

/sw.js
  Cache-Control: no-cache

How can I replace this value instead of appending it?

Maybe try adding this option: mergeSecurityHeaders: false

I know, this question might be outdated, but still...

If you set to false, it removes any default ones, which is a bit annoying, as I only want to replace one, but have to set to false, so need to manually reset defaults.
