Ability to Disable Prefix Information Option (Option 3) in ICMPv6 Router Advertisements

[jeandowve]

I would like to request the ability to disable the Prefix Information option (Option 3) in ICMPv6 Router Advertisements while retaining the IP Prefix Delegation (IP_PD) option in DHCPv6.

Disabling the Prefix Information option while retaining IP Prefix Delegation is important for scenarios where prefix advertisement is not desired or necessary. This feature would provide greater flexibility in network configuration and management.
