Multiple WordPress sites on single Redis server

Hello, I’m new to using Redis, Can I host multiple WordPress sites (60+) and use object caching (for the database) with Redis without problems?
I’m using Plesk with Litespeed EN.

as I read I can achieve that in 2 ways either by using different “Redis Database ID” Or different cache key salt parameters on wp-config.php like this:

define(‘WP_CACHE_KEY_SALT’, ‘sitewp1.com’);
define(‘WP_CACHE_KEY_SALT’, ‘sitewp2.com’);
define(‘WP_CACHE_KEY_SALT’, ‘sitewp3.com’);

*Note: Also each site uses a different table prefix.

The question is does the LSCache plugin use the parameter “WP_CACHE_KEY_SALT” or a different parameter? as the “WP_CACHE_KEY_SALT” used by the “Redis Object Cache” plugin, After I enabled the object cache from sitting with Redis it works fine but it didn’t add the “WP_CACHE_KEY_SALT” to the wp-config.php or should I do that manually?

What’s the right way to use Redis object cache with LSCache with multiple WordPress sites? I don’t prefer using database ID for each site and I don’t mind that all of the websites will use the same Redis database, I liked the way of using different cache key salt parameters and want to know the right way to do it with LSCache.

The last thing is there are a few keys in the wp-cofing.php but none of them “WP_CACHE_KEY_SALT” :

/**
 * Authentication Unique Keys and Salts.
 *
 * Change these to different unique phrases!
 * You can generate these using the {@link https://api.wordpress.org/secret-key/1.1/salt/ WordPress.org secret-key service}
 * You can change these at any point in time to invalidate all existing cookies. This will force all users to have to log in again.
