is card counting even possible in online blackjack?

so i'm always looking for ways to keep my edge, but i keep hearing conflicting things about card counting with online blackjack. i know with regular online blackjack, the decks get shuffled every hand or pretty often, so keeping count seems basically useless. but then there’s these live dealer tables now, and i’m seeing some people claiming it works there because of less frequent shuffles. i’ve never really tried tracking the shoe on a live dealer yet, but i’m curious if anyone has actually had any success or if it’s just more of the same hype. i just don’t see how casinos wouldn’t catch on or have some kind of counter. interested in what folks have tried or noticed.
