Customizing BBPress custom reply button


I have a few things that I need to do with my custom reply button.

1. Remove the reply button at the top.

On this page:

There is a reply button at the top of the page. I would like to make this one go away without hiding the one at the bottom, is this possible? To just display 1? First screenshot.

2. There is a button that says Reply and a button that says Create Topic, when either of these buttons are clicked, the button disappears. Is there any way to show a button that says Cancel and this button would then hide the form again?

Support access is open.
