Hi, I'm John! I will help you with this.
Do you currently have an active Microsoft 365 subscription linked to this account?
Microsoft 365 subscription is tied to the country and currency where it was originally purchased. Because of that, the system won’t let you extend the subscription or set up auto-billing using a payment method from your new country.
What you can do instead is cancel your current subscription and wait for it to expire (or you can cancel it early if possible). Once it’s fully expired, you can purchase a new Microsoft 365 subscription using your correct country and billing information.

I really hope this information is helpful! Let me know if you have any further questions or concerns.
