dhclient - can dhclient omit sending hostname to ISP DHCP server on WAN?

[viptux-opn]

Hi, new to OPNsense / testing for potential deployement [25.7.7_4]
Searched the forum about this, but didn't see any results specific to hostname.

With debian/network-manager, dhcp-send-hostname=0 omits sending hostname in the request to my DHCP server.
I've tested OPNsense WAN interface on a private network with a DHCP server and can confirm it's sending the hostname in the DHCP request even if hostname is unset in dhcp client options under WAN interface [GUI].

Is there a way to omit sending hostname information in the DHCP request to a DHCP server?


Many thanks in advance.
