Is it possible to temporarily disable SSL verification in Yarn to bypass the 'error unable to verify the first certificate' error, and is it advisable?

Yes, you can temporarily disable SSL verification using `npm config set strict-ssl false` (or `yarn config set strict-ssl false`). However, this is highly discouraged in a production environment because it compromises the security of your package installation. It's best used as a last resort for temporary testing or to diagnose the root cause.
