Lowering LCP Score for Performance Improvement

Has anyone had success lowering their LCP score (in regards to Google page experience) by reducing unused javascript? Or, are their any tactics you found useful in lowering the LCP score? this is my web esika.tiendabelcorp.cl
This is the link https://uatesika.tiendabelcorp.com/?workspace=performanceweb where he implemented several improvements. The problem I have is a skeleton in the home that has a height of 1360px and the 3 header images (esika, lbel and cyzone) have a lazy loading that I can not remove. These components have these classes VTEX-render-runtime-8-x-lazyload lazyloaded(for the 3 header images) and VTEX-render-runtime-8-x-slide(for the skeleton)
