More information about updating the firmware on your Raspberry Pi is available in the [https://www.raspberrypi.com/documentation/computers/raspberry-pi-5.html#updating-your-firmware official documentation].
Then restart <code>reboot</code> and the firmware will be updated (requires Internet access).
