LCP and Single Products page (flexslider?)

I am not a serious programmer, just enough to be dangerous, so sorry if there is a simple solution or I am crazy.

I have been reading on google vitals and the largest contentful paint. All of my pages are very fast on the site except the single products page.

I look at it in things like the webpage speed tests and I see the main images are downloaded in about the first 0.8 seconds. The flexslider js is loaded in under the first second, but the lcp is not until like 2.9 seconds. It seems that all the parts loaded and sitting there but no image shows for over 2 seconds.

So the question is, is there are a way to make the first image, a static image show in the spot until the js loads the slider? Is there a way to initialize the flexslider sooner rather than waiting until almost document complete?

I mean this is beyond my woocommerce knowledge, but it just feel like the parts are there to cut down the load time of a vital google measure by 70% with not too much trouble, I just can’t find it.

Any plugins? documentation? Anything to point me in the right direction?
