scroll by multiple images in an image gallery carousel block

Hi there, does anyone know of a code inject to allow me to modify the amount of images that are scrolled at once when navigating an image gallery carousel block?

I'm still on Squarespace 7.0 since 7.1 got rid of the music albums / audio players which is the main reason for my page, doesn't help that iframe embeds are a premium feature either, but that's a different topic...

Here's my page for reference: https://iamjonchau.com/

Right now it's really slow to navigate the carousel especially with the swiping animations, it'd be ideal if the carousel navigated by an entire page when pressing left or right. Even more ideal is if I you could swipe on mobile but I imagine that's much more difficult. Any ideas would be great, thank you!
