I'm unable to remove Temporal Upsampling

I am trying to remove Temporal Upsampling for a cinematic I’m working on, but neither disabling it through the console (r.TemporalAA.Upsampling 0) nor through the project settings seems to do it. I even looked at r.TemporalAA.Upsampling in my DefaultEngine.ini, and even there it’s set to “false”.

I’ve linked a picture of what my output log looks like when I try setting r.TemporalAA.Upsampling to 0 in the console.

Any help would be greatly appreciated!
