we try to make as hard as possible to root our devices as this action leave the device open to security risk.
Our solution to configure this devices (and the hostname that you're asking about in particular) using our Mobility eXtensions (Mx):

Let me know if this cover your request.
thanks for your fast reply that's great , i've looks but i think it's complicate ...

There is no root access and the system partition is mounted read only by default.
Host names usually are resolved via DNS.
Is there a particular reason, why you need entries in the hosts file?
ok thanks for this information ...
I'm a developer, for me network is complicate sorry
Some colleague ask me to add the ipaddress - url of a web site inside the host file that is for the reason
in this hosts file we can for example unauthorized facebook and so on ...so we'd like to update the host file
Inside the 4 walls using WLAN, this should be handled by a firewall.
To prevent a user from accessing unauthorized services via the public cell phone network, you need to lock down the device and whitelist the apps a user is entitled to install and use. You need to whitelist allowed web urls also. This can be done using tools like Enterprise Home Screen, AppGallery, Enterprise Browser (for details see Available Product Documentation - Zebra Technologies Techdocs). Or you can use a Mobile Device Management System to do that job.
As I stated above, a user can't edit the hosts file on a TC75. Apart from that it would be a very difficult task to keep that adress blacklist comprehensive and up to date.
