As it is written in this page:

A site should be able to declare that it does not want to be included in the user's list of sites for cohort calculation. A new interest-cohort permissions policy enables this. The policy will be allow by default. A site can opt out of all FLoC cohort calculation by sending the HTTP response header:

Permissions-Policy: interest-cohort=()


In /etc/apache/apache2.conf:

After the line of loading all enabled module (make sure headers.load is added in /etc/apache2/mods-enabled), and before the line of loading sites-enabled, add:

<IfModule mod_headers.c>
    Header set Permissions-Policy "interest-cohort=()"


Before the line of loading sites-enabled configure file:

In /etc/nginx/nginx.conf

add_header Permissions-Policy "interest-cohort=()";
