Set Expire Redis Full page cache

Hi these,
I use EE4 running wp woocomerce shop on amz ec2 t3.micro with 2vcpu-1G ram for code-php and another for remote Mysql.
Caching with --cache.
But i see in [phpRedisAdmin] that page cache auto delete in very sort time.
So anyone help me how can i increase this page cache time ?
Edit with define( ‘WP_REDIS_MAXTTL’, ‘2592000’ ); on wp-config or anywwhere?
Thank you.
