Hello there,

Try adding this CSS code to Appearance > Customize > Additional CSS from dashboard.

    @media only screen and (min-width: 992px) {
      .page #primary.col-md-9 {
        float: none;
        margin-left: auto;
        margin-right: auto;
      }
    }

That code will affect on all pages. For specific one, use the unique page’s ID class name. For example:

@media only screen and (min-width: 992px) {
  .page-id-162 #primary.col-md-9 {
    float: none;
    margin-left: auto;
    margin-right: auto;
  }
}

The ID number of your shared page is 162. You can get it with this plugin https://id.wordpress.org/plugins/reveal-ids-for-wp-admin-25/
