We are already passing bind-dynamic as an argument to dnsmasq. If it is not handled in some scenarios, please fix that. Otherwise, remove bind-dynamic from the arguments and keep it only in the configuration file. We should not maintain this option in both the config file and the dnsmasq arguments.

@snayak002c , May I know whether bind-dynamic is passed as an argument on bpi? I can see that its enabled only to specific platforms. https://github.com/rdkcentral/utopia/blob/main/source/service_dhcp/service_dhcp_server.c#L308

@aprasad-97 Its not an argument on BPI, Please make it available for all platforms. Either we can keep it in config file or pass it as an argument. Since we are passing it as argument for some platforms please see if we can enable it for all the platforms that way itself.Component owner is asking not to keep it as part of both.
