Customise WooCommerce Checkout Page (remove JS script)

I'm having a problem with my check-out page on WooCommerce. This is due to a Custom Theme that I can't remove right now, but it's causing problems with payment gateway plugins, like Stripe.

After some testing, I've found out that if some JS files from the custom theme were causing the problem at check out. I can't remove them completely as they will cause other problems across the site, but if I could make sure they don't load on the Check-out page only this will fix the problem.

I'm not very familiar with WP development, but are you able to write some code to remove one JS from the checkout page only?
If you check the source of the checkout, I need to remove this script (vendor.js) from https://curio2staging.wpengine.com/checkout/

I'll give priority to someone who could get this done asap at a reasonable fee.

Thanks, please let me know if you need more info on this issue.
