Is there any way to send such request, even with external libraries?
Nope. GET doesn't have a body. GET means you are trying to fetch a resource. So GET doesn't need any Content-Type header.
Multipart body is sent to upload something. That means it is used to create/update resource. So only POST & PUT works with multipart body. If someone is trying to use multipart with GET, it is conceptually wrong.
