This is a configuration value in the gateway, and can only be changed there (gateway web interface) by an admin user. The tags in the `System` provider are informational. (I don't think **any** of them are writable.)

Yes I can update directly on gateway however I am trying to write the tags with system.tag.writeBinding.

And you cannot. It is an informational tag. 🤷‍♂️
