So Could you please share me a method for fusing mac address to the another port

We currently don't have a specific guide on how to fuse mac address to another port. Do you require the mac addresses of other ports to also be obtained from efuse?

If you are planning on using Linux, you may be able to look at the following for information on how the default Linux SDK is able to fetch the mac address of another port. You could use this information to see if instead you can fetch the mac addresses of the other ports from a different method than efuse. https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1468819/am625-where-is-the-evm-u-boot-code-that-reads-eth1-mac-from-eeprom/5638880#5638880 

Here is additional background information on where the MAC addresses other than the one port that is efused comes from, from TI EVMs:
