Is there a way to overwrite Client Hostname?

in our current citrix environment, we use the variable clienthostname very often. citrix offers the possibility to define this manually (note clienthostname is the hostname of the client from which the client is started).

Now we would need a way to customize this also under Azure Virtual Desktop. Does anyone know a way we can implement this (whether via registryvalue, avd-uri-env...)?

Thanks
