How to disable desktop menu, top bar completely - use mobile menu at all widths

[adambundy]

Using latest FP version, what is the protocol for disabling the desktop menu completely and using the mobile menu always? Modifying that breakpoint is doable but I can't seem to get it fully disabled. Thanks much in advance for any help!

Updating here with the solution that worked for me. Rather than disabling the switch, I created a new breakpoint called 'uber' (> 9999px) which would never match. Then, I added data-hide-for="uber" to the .title-bar element:
<div class="site-title-bar title-bar" <?php foundationpress_title_bar_responsive_toggle(); ?> data-hide-for="uber">

I also needed to adjust the breakpoints in _navigation.scss:

// Navigation breakpoints
.mobile-menu,
.site-title-bar {
  @include hide-for(uber);
}
.desktop-menu,
.site-navigation .top-bar-left {
  @include show-for(uber);
}

Now the switch to the desktop menu never happens.
