Best way to handle Javascript

Hi, Google's new algorithm update is around the corner; the last time it happened I lost 60% of my traffic. But this time around, I have already started preparing and fixing my site.
I heard that the new update will be about Core Web Vitals, and possibly Mobile-only indexing. While optimizing my site, https://gamzo.in, I am facing a major issue, Javascript.
Scripts are contributing to about 70% of the total page load time. These scripts are ads and analytics, and I can't get rid of them.

I want to know the best way to handle the scripts. Like can we stop them to load until a user-interaction like scroll?
If yes, how do I do it?

PS: I am a noob in web dev.
