How to know when good quality movie torrents are available?

Right now I'm looking forward to watching two movies: "The Boy and the Heron" and "Godzilla Minus One"

Neither is on streaming services or BluRay yet. Which means that good quality torrents (IMO at least web-rip) are not available yet.

Is there a good way of figuring out when a decent torrent is available? I don't mean setting up some service like sonarr/radarr because those seem overkill (though my mind on this can be changed with a persuasive argument). Rather maybe some website I can check? Thanks.
