Google page insight score for NextJs website with Server Side rendering

Question

I am using NextJS + React-Redux + SSR + Express JS + MDBREACT. For normal page my google page insight scores is average, But when I put google ads into some page the page insight score decreased drastically.

When I am looking into the Opportunities on google page Insight. I got two major things related to payload key requests.

1. For google ads
2. For MDBreact fonts I tried to use lazy loading using loadable package of react but when I apply that I got the same results.

I have tried lazy loading using @loadable/component react package. I have tried async too

I like to increase my score with google ads upto 70+ for the pages which include google ads.
