Don't appear to have this feature. The TV sets are produced for regions. If a region's laws create issues the recording "code" isn't in to TV so no surprise it doesn't work.

On top of that, it's a safe bet the hardware to record would be missing since that region would not require it.

If you want to record from Antenna there are OTA recorders like Channel Master, the Amazon unit at https://www.amazon.com/Fire-TV-Recast-over-the-air-DVR-500GB-75-hours/dp/B01J6A6H74 and others.
