Looking place holder for MAC address in AGX Orin Module EEPROM

Looking place holder for MAC address in AGX Orin Module EEPROM. Is there way to write 6 byte data and read it back ?

I tried to write one byte using 2cset -y 0 0x50 0xb2 0b,
But ethernet did not up. I reverted changes. Please can you guide me , where i can save another MAC id ?

There is no method to read another mac address from eeprom as there is only one MAC address in eeprom.

Are we talking about MGBE or RGMII?
