What will be the expiry time, when we set SESSION_DRIVER / CACHE_DRIVER as redis in Laravel?

Session lifetime is set as below

'lifetime' => 10080

Now I just want to set an expiry time when we set "SESSION_DRIVER" as Redis

SESSION_DRIVER=redis

If we set "CACHE_DRIVER" as Redis cache instead of file what will expire time or how can we set expire time for "CACHE_DRIVER"

CACHE_DRIVER=redis
