Updates applied to staging WordPress site affecting production even with different databases

I have resolved my issues by reviewing the Redis Cache plugin installation guide and making the following changes inside the wp-config.php files on each WordPress installation.

The define( 'WP_REDIS_PREFIX', '' ); was added with the values set as production, staging, and beta for each respective site.

The define( 'WP_REDIS_DATABASE', 0 ); values for the staging and beta sites were change to 1 and 2 respectively.

After making these changes, the cache data collision issues were resolved and there was no longer any data being overwritten between the websites.
