Is it possible to customize the content displayed on a webpage

[mattyx0011]

I have currently set everything up using Docker, but the webpage includes a 'nav-link go-pro-link' that links to 'stirlingpdf.com/pricing,' as well as a 'Powered by Stirling PDF' link that connects to an external URL. Could you please let me know if it’s possible to customize or remove these links? I would like to prevent users from clicking and uploading files to external URLs.
I will be grateful for any help you can provide..

<a href="https://stirlingpdf.com" class="stirling-link">Stirling PDF</a>

<a href="https://stirlingpdf.com/pricing" class="nav-link go-pro-link" target="_blank" rel="noopener noreferrer" <span class="go-pro-badge">Upgrade to Pro</span>>

Have you found a way? This is very annoying. Stirling was awesome until they added adware in my homelab. The whole point of selfhosting is not to have to deal with this kind of spam. I understand Stirling has to be profitable but this is in no way going to help sell more subscriptions. I will never pay for it, I don't want to see this badge.

Please Stirling, remove this and keep the powered by sterling pdf at the bottom.
