Is Cinavia a thing in the AC3 tracks of DVDs?

As the title says.

As we all know, Cinavia is already a thing in the DTS tracks of DVDs to prevent people from remuxing them to a Blu-ray. However, has anyone heard of Cinavia in the AC3 (Dolby Digital) tracks of a DVD?

Cinavia was independent of the codec since the protection was in the waveform.

DVDs that have a AACS folder have Cinavia. But the actual number of DVDs that had Cinavia was small compared to the number of protected Blu-ray titles.

Cinavia is basically dead. It hasn't been released on a disc since 2018. Of course if you have an older disc, that will still be protected.

Also, except for hardware Blu-ray players and similar devices, no one supports Cinavia any more. Most, if not all streamers, like Apple TV, Amazon Fire, Zidoo, etc do not support Cinavia restrictions so it gets ignored
