How to remove discovery.zen.ping.unicasts completely

Elastic Stack Elasticsearch
1

I am running a Elasticsearch 7.2 version and I had a property defined in my Elasticsearch.yml file that is - discovery.zen.ping.unicast.hosts: [IP1, IP2....]
but obviously when I read the documentation I see that this discovery.zen.ping.unicast.hosts: property is not supported any more starting elasticsearch7.x and have been replaced with discovery.seed_hosts:[IP1, IP2] so I did that change today and restarted the nodes and the cluster came up green in health with no problems however when I hit cluster settings API that is -
http://localhost:9200/_cluster/settings?pretty&include_defaults
I have commented the discovery.zen.ping.unicast.hosts: completely and only has discovery.seed_hosts in my Elasticsearch.yml
I still the ZEN property nested inside discovery ( on 4/5th line below response from cluster setting api ) so I wanted to know how can I completly remove zen or what am I doing wrong here, sorry I am new to ES so maybe you guys notice anything or should be able to help me out.

Elasticsearch 7.2 is EOL and no longer supported. Please upgrade ASAP.

These settings are still there in 7.x for compatibility reasons. To remove them completely, upgrade to 8.x.
