Is this possible to set custom url scheme as baseURL in axios? What I want to achieve:

const axiosInstance = axios.create({baseURL: 'my-custom-scheme://'})
axiosInstance({methods: 'GET', url: '/some-other/endpoint'})

and I want my get call to be done to my-custom-scheme://some-other/endpoint. but what I am getting in my-custom-scheme:/some-other/endpoint.

The problem is axios is replacing my // with / making it impossible to set custom url scheme as baseURL. Is there any way to achieve the above?
