I want to add for a particular page.
But my pages are rendered inside one HTML
Try
document.head.innerHTML += '<meta http-equiv="X-UA-..." content="IE=edge">'
You can add it:
var meta = document.createElement('meta');
meta.httpEquiv = "X-UA-Compatible";
meta.content = "IE=edge";
document.getElementsByTagName('head')[0].appendChild(meta);
...but I wouldn't be surprised if by the time that ran, the browser had already made its decisions about how to render the page.
The real answer here has to be to output the correct tag from the server in the first place. (Sadly, you can't just not have the tag if you need to support IE. :-| )
$('head').append('<meta http-equiv="X-UA-Compatible" content="IE=Edge" />
');
or
var meta = document.createElement('meta');
meta.httpEquiv = "X-UA-Compatible";
meta.content = "IE=edge";
document.getElementsByTagName('head')[0].appendChild(meta);
Though I'm not certain it will have an affect as it will be generated after the page is loaded
If you want to add meta data tags for page description, use the SETTINGS of your DNN page to add Description and Keywords. Beyond that, the best way to go when modifying the HEAD is to dynamically inject your code into the HEAD via a third party module.

This may allow other meta tags, if you're lucky
Additional HEAD tags can be placed into Page Settings > Advanced Settings > Page Header Tags.

Like this ?
<script>
var meta = document.createElement('meta');
meta.setAttribute('http-equiv', 'X-UA-Compatible');
meta.setAttribute('content', 'IE=Edge');
document.getElementsByTagName('head')[0].appendChild(meta);
</script>
