Unfortunately, register link ist not something you can activate via settings for this part of forum.

You need to modify this file: form-user-login.php

Best way would be to create a bbpress direcrory in your child theme and copy this file there and modify.

You can also make use of the [bbp-register] shortcode.

I hope this helps.
