DHCP Option 160 via Vyos 1.4

Hello Community and TIA.
Need to send a URI via option 160 to VoIP phones from Vyos 1.4.
The string would be in this format. https://user:[email protected]
It includes the protocol, username:pass and a FQDN.

Need specific config examples showing correct syntax.
I assume it would look like this but I’m sure I have syntax errors.

set service dhcp-server global-parameters ‘option option-160 = string’
set service dhcp-server shared-network-name NET01 subnet x.x.x.0/24 subnet-parameters 'option option-160 “https://user:[email protected]

Thanks again.

Just bumping this post.
