How to make an undetectable get post request

If you add some browser headers, cookies, then your http request will be similar to real browser

Depends on websites antibot system.
Websites can add some javascript, that generates some data, needed in your required get request, so that when you send GET request without that data, it will fail 100%

With all that said, I'm not saying this is not possible to make, but it will be impossible to make just single GET request and get it like real browser. So it greatly depends.
