I suppose you can disable NV read function in MT command to disable the read.

If we disable that function then how will we take backup of znp?

If you disable it, you cannot backup it anymore.

provision of backup ZNP and protection from attack , both features are important and required.

Then, you might need to implement some kind of encryption in NV storage.

Hello Dhanraj,

You will need additional security functionality on the UART channel such as host passwords or packet encryption which is not included on the provided ZNP solution.

You have to add it to your application, TI does not provide any method or documentation so you are free to implement it as you prefer.
