Answering my own question, the correct syntax is

nmcli c modify 'Wired connection 2' ipv6.routes ' 2001:db8:c111:b000::/56 '

This results in a line in the nmconnection file ipv6 section of

route1=2001:db8:c111:b000::/56

While this does not explicitly attach the subnet to interface eth0, this
is done by activating the profile on device eth0
