How can I make an Angular service injectable only within a specific module?

I am trying to create a service in Angular that should only be injectable within a specific module, not accessible outside that module.

I have a service MyService that I want to restrict so it can only be injected within MyModule and not in other modules of the application.

MyService (my.service.ts):

import { Injectable } from '@angular/core';
@Injectable({
providedIn: 'root' // This allows the service to be available globally, which I want to avoid
})

export class MyService {
constructor() {
}
}


MyModule (my.module.ts):

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { MyService } from './my.service';
@NgModule({
declarations: [],
imports: [CommonModule],
providers: [MyService] // Service should only be injectable here
})
export class MyModule { }


I want MyService to be injectable only within MyModule, and if I try to inject it into components or services in other modules, it should not be available.

I Tried:

1. 
   Providing the service at the module level (providers: [MyService] in MyModule).
   
   
2. 
   Avoiding providedIn: 'root' to limit global injection.
   

How can I ensure that MyService is only injectable within MyModule?
