Currently the default setting is the title of the bbpress forums to be underlined. How can I remove the underline text decoration?

I think that is inherited from your theme. Link to exactly what you are talking about though.

The links are like this because that is how it is in your theme.

You can try this custom css to remove the underline. Place the custom css in your child themes custom css or anywhere else you can place custom css like a plugin or theme.

.bbpress .post-content a {
    text-decoration: none !important;
}
