The space of option numbers in DHCPv6 is not the same as the space of option numbers in DHCPv4. Just because option 3 in DHCP4 sets the default route, doesn't mean that option 3 sets the default route on DHCPv6 - option 3 does something completely different in DHCPv6. The same is true for option 6 - the option NUMBER for the DNS server in DHCPv6 is 23. The function of option 3 in DHCPv4 is done using router advertisements in IPv6 land - there's no direct equivalent of the DHCP option at all, and for a generalised static route, I don't believe that a DHCPv6 option has been defined. There's an expired draft proposal which is insanely complex, https://datatracker.ietf.org/doc/html/draft-ietf-mif-dhcpv6-route-option-05 But it has never been ratified as an RFC.
