How to register the MAC address of my own board which STM32MP151CAA3 is mounted on?

[HMasu.1]

I want to register the MAC address of my own board which STM32MP151CAA3 is mounted on.

Can I use STM32CubeProgrammer to register the MAC address?

If so, are the following commands correct?

 Example)

 MAC address which I want to register: 00:12:34:56:78:90

 > STM32_Programmer_CLI -c port=usb1 -otp program wordID=0x39 value=0x56341200
 > STM32_Programmer_CLI -c port=usb1 -otp program wordID=0x3A value=0x00009078

Also, can I update this OTP bits only once?

(If I register the MAC address once, Can't I update it again?)

Best regards
