Change WiFi manufacturer on Xiaomi phones

hey guys,
'
So the situation is my office is blocking all phones wifi access by blocking MAC address. They use Advanced ip scanner which shows them that the device is from xiaomi



I want to Change name and Manufacturer name in sync with the PC over there so that they cannot identify that it's a mobile device. How can i do this?

Please see I am Rooted and i have also tried to locate this in build.prop but i was not able to locate . awaiting for your replies.

Thanks
