You just need to request option 17, which you need to do like so:

option dhcp6_vivso

Then tell dhcpcd.conf how to interpret the option.
dhcpcd-definitions.conf has this example:
##############################################################################
# Vendor-Identifying Vendor Options
# An example:
#vendopt 12345  encap                   frobozzco
#encap 1        string                  maze_location
#encap 2        byte                    grue_probability

see here for it being tested on dnsmasq:

I've not tested it recently, will try and do so later.

Good luck!
