Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
When a Microsoft subscription is created, that becomes associated to the Microsoft account used as a digital licence, there is no native method available to move the subscription to another Microsoft account.
The only available option would be to cancel the subscription on that account using the steps provided on this link, then take out a new subscription on your preferred Microsoft account.
After you take out the new subscription, you will still have access to your files and OneDrive on the new account that you previously shared with, but if you no longer use the original account, you would loose access to the OneDrive on that account, so it would be best to backup all your files from OneDrive on that account before changing the subscription.
