Ability to not use nuro device at all #2

Hi, I have unifi nano g GPON device lying around. If I used serial hack to change serial/mac would nuro work with it?
Do you know what kind of protections does Nuro have to identify if it's correct device.
If it's just serial and mac then I should be ok?
I dont want to get nuro and then find out that I can not use my own router, but NTT vdsl speeds are getting worse, so I am on fence to go nuro again...

Thank you again for your work on this, it's really sour experience when talking with nuro support, they take you for a fool.
