I’ve just added that capability to one of my existing shortcodes in my style pack plugin, so if you install
https://wordpress.org/plugins/bbp-style-pack/
and then see
Dashhboard>settings>bbp style pack>shortcodes for a description of how to use it in detail, but
[bsp-display-topic-index noreply='true']
used in a page will get you what you want
@aviazz
You already should have a way to view topics with no replies. By default bbPress has a feature called Views. It allows you to display topics with various different arguments. Topics with no replies should be one of the 2 default views which are Most popular topics and Topics with no replies
You can link to the existing page using the Topic Views widget in your sidebar, or you can use a shortcode already provided by bbPress to display a view shortcode in a page and add it to a menu. You can also also instead add a custom link to a menu in the menus section in Appearance > Menus if you do not need to use a shortcode in a page.
The widget is called the Topic Views widget that you will be able to see in Appearance > Widgets or you can manage your sidebars using the Customizer API in Appearance > Customize in the WordPress backend.

The shortcode you would want to use is [bbp-single-view id='no-replies']

If for some reason you may not already have the default view. See if its related to a theme/plugin function removing the default view by troubleshooting.
