We'll have to adapt the existing template and override the existing handler:

1. Override the qweb template in a file called views/templates.xml:

<?xml version="1.0" encoding="UTF-8"?> 
<odoo> 
  <template id="show_website_info"  
            inherit_id="website.show_website_info">
    <xpath expr="//dl[@t-foreach='apps']" position="replace"> 
      <table class="table"> 
        <tr t-foreach="apps" t-as="app"> 
          <th> 
            <a t-att-href="app.website"> 
            <t t-esc="app.name" /></a> 
          </th> 
          <td><t t-esc="app.summary" /></td> 
        </tr> 
      </table> 
    </xpath> 
  </template> 
</odoo> 

2. Override the handler in a file called controllers/main.py:

from odoo import http 
from odoo.addons.website.controllers.main import Website 
 
class Website(Website): 
    @http.route() 
    def website_info(self): 
        result = super(Website, self).website_info() 
        result.qcontext['apps'] = result.qcontext['apps'].filtered( 
            lambda x: x.name != 'website'
        ) 
        return result 

Now, when visiting the info page, we'll only see a filtered list of installed applications, and in a table as opposed to the original definition list.
