Foreman » Installer

when running the foreman-installer with the following options:
foreman-installer \
--scenario katello \
--foreman-proxy-dhcp-provider remote_isc \
--foreman-proxy-plugin-dhcp-remote-isc-dhcp-config /path/to/nfs/mount/containing/dhcpd.conf \
--foreman-proxy-plugin-dhcp-remote-isc-dhcp-leases /path/to/nfs/mount/containing/dhcpd.leases \
--foreman-proxy-plugin-dhcp-remote-isc-key-name my_omapi_key \
--foreman-proxy-plugin-dhcp-remote-isc-key-secret my_secret \
--foreman-proxy-plugin-dhcp-remote-isc-omapi-port 7911 \
--enable-foreman-proxy-plugin-dhcp-remote-isc \
--foreman-proxy-dhcp-server my_server_ip

it says :
"stderr": "ERROR: Unrecognised option '--foreman-proxy-plugin-dhcp-remote-isc-dhcp-config

I'm running theforeman 1.21 katello 3.12

if I manually configure the smart proxy in /etc/foreman-proxy/settings.d it all works fine, but it's kinda annoying that I need to do this each time foreman-installer is run.
