Where you see it
On the Add-ons page the item shows "later, with a partner" and the planned price, and in the quote form "Coming soon, about" and the price. You cannot add it yet: it has no button.
Why it is shown already
So you know in advance what to expect and can plan with it. The planned price is an estimate; the final price comes when the item can be ordered.
If you need it now
Describe what you want in the portal as a custom request. We will look at it and reply.
Let us look at your site.
The quote form takes two minutes: package, add-ons, your company details. You see the price at once, and it commits you to nothing.
