Hide or Overwrite website referrer in NGINX

I am looking for a skilled freelancer who can help me hide the traffic sources on my website permanently. The goal is to prevent analytics tracking and protect user privacy. I am not sure if I require a detailed report or analysis of how the changes will affect my website traffic.

Ideal Skills and Experience:
- Experience with NGINX server configuration
- Knowledge of website referrer hiding techniques
- Familiarity with privacy protection and analytics tracking prevention best practices
