Can the width of the nav bar be increased?

I'm working on hbcusoutside.com   password: grizzly

The nav bar breaks into two lines at an unfortunate width. There's plenty of horizontal space if the container can be extended. Failing that, I'd prefer the hamburger to kick in rather than break the nav bar into two lines. I do prefer having the nav bar visible so I don't want a solution that just uses the hamburer 100% of the time.

Can the nav bar area be extended horizontally?

Can the nav be restricted to never break and rather trigger the hamburger?

Worked perfectly. Thanks!
