Csg M106 Router - Looking for DHCP Vendor Option settings

I need to configure some specific DHCP Option #s for some IP phones I am trying to test

They need an Option 43 configured. Would anyone know where I may find these settings from the Web Interface or LUCY interface?

Thank you

Look in LuCI → Network → Interfaces → LAN → Edit → DHCP Server → Advanced Settings → DHCP-Options.
