How to get LCP < 2.5s on Mobile Product Page (Debut theme)

We're trying to achieve LCP < 2.5 on PageSpeed for our product pages. However, while we're in the range of 2.7-3.0s, we struggle to get the last steps added.

 

One recommended step we've encountered has been to preload the product image - but we're unsure if this is already done by default in the Debut theme via `lazypreload` from `lazysizes` - and if not, how we'd achieve it for responsive images within Liquid. Any suggestions on this?

 

In addition, we have a number of add-ins like Infinite Options, which we'd like to "defer" loading off. We've tried to do this via putting the loading into our footer and using "defer", but these scripts seem to still load before the LCP is reached. Any suggestions on how to generally handle this kind of challenge?
