I'm afraid it's not possible to change these pins as they function as the hardware I2C interface (A4 = SDA & A5 = SCL) and so cannot be moved.

However the I2C interface is designed to allow multiple I2C devices to be connected to it at the same time. Hence why each device needs to have its own address assigned to it. So as long as your screen, and the library you are using for it, allows other device to be connected at the same time it may be possible to connect both this sensor and your display to these pins at the same time.
