Hexo - how to override generated meta tags?

I'm working on my blog and i'm using Hexo. The thing is, i want to override the following meta tags:

<meta property="og:type" content="website">
<meta property="og:title" content="Borgez">
<meta property="og:url" content="http://feliborgez.github.io/blog/index.html">
<meta property="og:site_name" content="Borgez">
<meta property="og:description" content="The personal blog of Felipe Borgez">
<meta name="twitter:card" content="summary">
<meta name="twitter:title" content="Borgez">
<meta name="twitter:description" content="The personal blog of Felipe Borgez">

The thing is, it is not being generated on my template engine, inside the Theme, so i could just replace it. So, where it is being generated and how can i change it?
