Setting host-decl-name should fix this problem but vyos is not letting me save the config with this parameter set!
After setting this parameter and committing changes, It generates a temporary file at /tmp/dhcpd.conf.
That file looks like this,

use-host-decl-names on; was added separately so that’s why it’s repeated in the config.
In dhcp_server.py, It adds use-host-decl-names on; if host-decl-name was set and then it checks for the value of host-decl-name at 2 other places. at one of these places, the check fails and it adds shared network name as prefix.
Manually setting use-host-decl-names on; will not fix the problem because it’s still looking at the host-decl-name parameter in vyos config.
so now I have to figure out why vyos won’t let me set this parameter in vyos config.
