How to change the country or region of my Apple ID?

Hello guys. I am currently in the USA. I need to change the region for map binding and other things. I can't change the region because I have a subscription to apple musik and I can't unsubscribe from it. Since in the requirements you can change the region only at the end of the apple musik subscription. Is there a support link where I can go to unsubscribe?. Even if there is no refund. Thank you
