You can simply decline by stating to an agent that you do not want your photo taken and want to opt out of a face scan. From there, a TSA agent should follow standard procedure of looking at your ID and your face to verify your identity.
They should have said, but I guessing they didn’t because it’s easy and indicates it at the checkpoint. You tell the agent you are declining the biometric identification. Do it as soon as you hand the agent your ID, don’t step in front of the machine, then follow instruction (probably step alongside so they have a clear view of your face).
Nothing in this story says how I can opt out right now.
Great, are they going to deliver the TSA agent to my house?

I can’t do that right now.
