Can I hack, mislead or deceive Core Web Vitals?

Probably not in such way. Obviously you could create very lean pages for Google's PageSpeed Insights testing, resulting in optimal "Lab data". However, it is the "Field data" that counts towards Google ranking and you can't hack the devices and network conditions of your visitors. You could implement best practices though, helping your overall score as well as real users.

For example, you could choose to also serve lean pages to real visitors. This is more of a best practice than hacking though, as lean pages are good for real user experience, which eventually is the purpose of Core Web Vitals.
