Unfortunately, it is not possible to change the type of QR Code already created.
A Dynamic QR Code, once generated, cannot be converted into Static QR Code or vice-versa. You will need to create a new QR Code.
In a Static QR Code, linked data (say URL) is hardcoded in the QR Code data modules (black-and-white square blocks). This is why it is not possible to change the content or type.
In Dynamic QR Code, the linked content is not directly hardcoded in the QR Code data modules. So it is possible to edit the content of the QR Code but still not the type.
Note: If you've created a Dynamic QR Code, it is possible to edit the content category of the QR Code (say from Document QR Code to Website URL QR Code). You'll need to reach out to the support team for this as this action is currently not possible via the dashboard.
