How to remove Privacy browsing from my iPhone

You can't remove the private web browsing feature. It's part of Safari's code. Just don't use it if you don't want to.

If you are worried about your website choices being recorded by your phone, you can take the following steps

Delete Historical Data

Firstly, you can take steps to remove information that your iPhone recorded about those sites in ⚙️ Settings app:

Settings→Safari→Clear History→(select which history to clear e.g. 1 Hour)→Clear History

There may be additional Website Data you can clear here:

Settings→Safari→Advanced→Website Data→Edit->(select a site)→tap "⛔️ Example.com"

The OP's question is phrased as if they are not a native English speaker. There is no data or feature exactly called "Privacy Browsing" on iPhone.

I chose to interpret his question as

"How do I remove *evidence* of my private browsing from my iPhone".

You chose to interpret it as something different. That's fine too.
