How to mass-enable Endpoint MFA on client PCs

How to mass-enable Endpoint MFA on client PCs

Hello, we are trying to roll out Endpoint MFA to all of our Windows computers. I've configured the policy settings we need but am looking for a way to mass-enable Endpoint MFA in the installed agents. From official documentation I am reading that for Endpoint MFA to be active on a computer, you must install the agent from within the AdSelfservice admin console. This is incredibly tedious to monitor and maintain as we have over 1300 computers. Is there any other way to do this? Registry key? Anything?

Thanks,
Mike
