It is not a part of angular 9, it is released with Angular 11 by default. You should upgrade the angular version and ready to use it.
Main reason: Earlier even making a smaller change trigger angular dev server to re-compile and process all the files again which takes time to re-render and re-paint everything with HMR it will be quick. It takes a lot of time based on your system configuration.
HMR is not a angular feature, but it is a webpack feature and bundled in the angular 11 version by default. HMR is to update the application modules without reloading and repainting everything.
How to use it:
ng serve --hmr
