Pasing Google Core Web Vitals

We are digging into ensuring our community is performing on Google. One of the issues we ran into is that Google is reporting some issues with a majority of our pages:

It appears our largest issue is CLS (Cumulative layout shift). Has anyone discovered a way to make this passable within Verint?

Another one of the largest issues appears to be "Eliminate render-blocking resources". Has anyone seen this and discovered a way to resolve this? It appears to me that the less is being complied on page load, is that a correct assumption? Should we look into just serving compiled CSS to our visitors?
