Customize touch bar button when using the browser? Can I turn off the touch bar when I use the browser like Chrome or Safari?

Sometimes, I click the Reload button unknowingly when I fill the website form. This is a nightmare for me, especially for filling long questions.

I only found this article from official,
https://support.apple.com/en-us/HT207055#customize

But it doesn't mention how to customize setting except for default touch bar.

OSX: 10.14

Update

I want to get rid of the reload button like the following.
Menu Bar → View → Customize Touch Bar

Drag the reload button on your Touch Bar into the trash can on the far left side of your Touch Bar (or just off the Touch Bar).



More info from Google.
