It seems that it's not a  restriction in RFC 2132, as comparison dnsmaq can
offer a no-router-ip option.

So could ovn remove this restriction or is there anther way to meet the
requirement?
It took me a while to figure out what you're talking about.  Are you
asking whether options:router could be changed from mandatory to
optional in the DHCP_Options table for DHCPv4?
Yes, i think it's better to be optional.
