Thanks Melissa!
I was able to switch the pages type by editing the handlebar file like you said. An additional step was updating this line:
<div class="Answers-container Answers-resultsWrapper Hitchhiker-3-columns">
by adding “Hitchhiker-3-columns” to the end.
and updating this line:
<div class="Answers AnswersVerticalGrid CollapsibleFilters">
by changing Standard to Grid.
This post was helpful to reference: Changing vertical-grid page layout from 3 columns to 2 columns
