Mock Axios requests only for specific URLs, otherwise perform original request

I need to use stubs for requests to external resources, but still I need to fulfil requests for internal resources. Is it possible to mock a request from Axios only for certain URLs and otherwise continue to execute the initial requests?

export const spyOnAxios = (expectedResponse) => {
return jest.spyOn(axios, 'post')
.mockImplementation(function () {
    if (arguments[0] === 'https://external-api.com') {
        return expectedResponse
    }  
    return performOriginalRequest()
})}
