DHCP client settings to mitigate TunnelVision VPN decloaking issue?

Recently there has been some news about a DHCP option that can be abused to allow decloaking VPN connections. The write up is here. I saw someones twitter post suggesting dhcpcd settings changes to mitigate. iirc Nix uses dhcpcd by default. I’m mostly curious if anyone here has already deployed any these mitigations on nix and have examples or suggestions?
