I found the answer to my own problem:

Have a look at 
https://github.com/isc-projects/kea/blob/master/src/lib/dhcp/docsis3_option_defs.h 
.

I ended up with something like this in my config:

             "option-data": [
                 {
                     "name": "syslog-servers",
                     "space": "vendor-4491",
                     "data": "2607:f249::3a"
                 },
                 {
                     "name": "config-file",
                     "space": "vendor-4491",
                     "data": "cm/012345678.cfg"
                 },
                 {
                     "name": "time-offset",
                     "space": "vendor-4491",
                     "data": "-25200"
                 },
                 {
                     "name": "tftp-servers",
                     "space": "vendor-4491",
                     "data": "2607:f249:20:1::5"
                 },
                 {
                     "name": "time-servers",
                     "space": "vendor-4491",
                     "data": "2607:f249::33,2607:f249::34"
                 }
             ],
