Javascript – Overriding interface property type defined in Typescript d.ts file

javascripttypescripttypescript-typings

Is there a way to change the type of interface property defined in a *.d.ts in typescript?

for example:
An interface in x.d.ts is defined as 

interface A {
  property: number;
}

I want to change it in the typescript files that I write to 

interface A {
  property: Object;
}

or even this would work

interface B extends A {
  property: Object;
}

Will this approach work? It didn't work when I tried on my system. Just want to confirm if it's even possible?

I use a method that first filters the fields and then combines them.

reference Exclude property from type

interface A {
    x: string
}

export type B = Omit<A, 'x'> & { x: number };

for interface:

interface A {
    x: string
}

interface B extends Omit<A, 'x'> {
  x: number
}
