Changing your account region

Hello, I would like to know when I can change the region in my account settings after canceling my apple music subscription - Or is it possible to change the region without waiting for the end of the subscription to Apple music that I canceled (bold mine)

I'm afraid not. All of the below must be done to change regions:

• Spend any balance remaining on your Apple ID. If you're not sure whether you have a balance, check your Apple Account balance.
• Cancel your subscriptions and wait until the end of the subscription period. 
• Wait for any memberships, pre-orders, movie rentals, or Season Passes to complete, and wait for any pending store credit refunds to process. You can cancel a pre-order.
• Make sure that you have a payment method for your new country or region. See what payment methods you can use.
