Remove drag events on Woocommerce single product flexslider image gallery (on mobile)

I am overall happy with using flexslider on mobile. However, I have implemented an overflow scroll on my horizontal thumbnails on mobile (They’re css’d to sit horizontally below the current slide). When I drag on the overflowed thumbnails, left or right, it progresses the current slide to the next/previous and won’t allow the overflow containing the thumbnails to be scrolled.

Current slide with thumbnails below

How can I disable the events causing the slider to progress to the next/previous slide when dragging on the current thumbnails? I only want the slider to progress on a thumbnail click.

I’ve tried the woocommerce_single_product_photoswipe_options and woocommerce_single_product_carousel_options filters which did not seem to have what I needed. A thread suggested dequeuing and enqueuing a custom woocomerce flexslider.js file but I’d like to avoid this.
