Can you set the Host header using fetch API

I have a reverse proxy server, which redirects you to different services depending on the Host header.
However when making requests to this server using a browser, the Host is always set to the domain name in the URL. I tried:

fetch(http://foo.com, {headers:{Host:bar.foo.com}})

But it doesn't work

Host is one of the forbidden header names:

A forbidden header name is an HTTP header name that cannot be modified programmatically.
