At the moment the banner is applied on the site globally and the option to set a custom banner for a specific page is not available, we will try to add more popup options in future updates.
However, if you are looking to show the banner only for a specific page and to disable it for the rest of the website pages, you can use the following code snippet into Theme options > Layout > Advanced > Custom header tags include:
<style>
body:not(.page-id-1234) .pix-banner { display: none !important; }
</style>
Where 1234 is the page ID and you should replace it with the your page ID where you want to show the banner (the HTML class "page-id-1234" is added by default by WordPress to the body tag of each page).
For example, to find the page ID on your website you can check this article.
