Correct way to use wp_cache_key_salt with wp_redis_database?

Hello.

I run a few WordPress websites on single VPS server and all websites`s database are seperated. (Ubuntu 20.04 + Mariadb + Php7.4 + Nginx)

In this case, is it correct to set it below in each wp-config.php ?

define( 'WP_CACHE_KEY_SALT', 'first-website.com' );
define( 'WP_REDIS_DATABASE', 0 );

define( 'WP_CACHE_KEY_SALT', 'second-website.com' );
define( 'WP_REDIS_DATABASE', 1 );

define( 'WP_CACHE_KEY_SALT', 'third-website.com' );
define( 'WP_REDIS_DATABASE', 2 );
