Show the profile switcher but not the Input field saying Choose starting place, and choose destination.

[aasutossh]

controls: {
          profileSwitcher: true,
          inputs: false,
          // instructions: false,
        },

disables the profile switcher too.

So, I did a bit inspecting and did

.mapbox-directions-origin,
.mapbox-directions-destination {
  display: none;
}

Try it.
BTW, after trying all these modules and kept getting into issues. I used plain mapbox gl js. It solved most of my problems.
