How to remove [comment] section on my blog post/page?

The first way to disable WordPress comments is to simply use the already built-in options within WordPress.
Within a WordPress post or page itself, you can click into the “Screen Options” at the top right and enable the ability to see the “Discussion” options.
Then scroll to the bottom and you will have the option to turn off and or “not allow comments” on your blog post or page. The one drawback to this is that has to be done on an individual post or page level, there is no global option.
The second option you have is to globally disable discussions. You can do this by clicking into “Discussion” under Settings in your WordPress dashboard and then un-checking the option “Allow people to post comments on new articles.” The drawback to this method though is that it doesn’t affect older articles, only new ones.
Also, you can use a plugin for this feature.
