How to Disable Lazy Loading of Images on a certain post?

Hi,
I have been using Jetpack for around 2 years now. Love it.

I wanted to disable lazy loading of images on one particular post only. (not the full site)

I searched a lot on the web. I came across this official page (https://jetpack.com/support/lazy-images/). It says ‘For example, if you don’t want lazy images to run on a certain page, you could hook in and disable lazy images for that page.‘

The sad part is, I am not a developer and I do not know what to do with code (lazyload_is_enabled). What is ‘hook in?’ I do not know where should I use and how should I use it? Should I use Post ID and then what? Should I use a plugin like Insert Headers and Footers or something?

Please tell me how can I disable lazy loading on a particular post. If you tell me the steps, it would be great.

Thank you very very much for your kind support.
