No, because you need to configure the servers interfaces somehow !
You cannot reasonably configure them from a DHCP service running on
the same server and so they should be statically configured.
Creating a host declaration as shown will simply prevent the server
handing out a lease - it won't stop the client asking for one, or
complaining when it gets no response.

What do you mean by "... keeps telling that it has no wired network
..." ? Is this in the logs (which logs ? what process name ?) or
somewhere else ?
"dhcpd if1" is not a valid statement for the dhcpd.conf file. It's
something that is passed via the command line, so is either part of
the command file that loads the dhcp service, or a config file read
by it.
