New nintendo 3ds xl mac address change without sd card reader?

My father has made in my nintendo ei wireless lock in the only allows me an hour of Wi-Fi per day

A friend has told me that I only need to change the mac address to bypass the lock allerdinds I do not know how to change the mac address. Thank you ever for all the answers (please do not send videos).

A MAC address is "burned in" the hardware.

Apart from that, a change in the MAC address (which is feasible on the PC, for example) is no use at all, if your father has correctly configured the router, then he will not allow any new WLAN devices and you will come back exactly zero hours a day in the Internet.
