No, you cannot change the URL of a static QR code once it has been generated. A static QR code is a fixed code that contains a set amount of information that cannot be changed. If you need to change the information that the QR code contains, you would need to generate a new QR code.
On the other hand, if you need the ability to change the URL or other information
contained in a QR code, you can use a dynamic QR code instead. Dynamic QR codes are codes that can be edited and updated after they have been generated.
