From my experience, I never saw a PhD program advertising remote work, but in practice, it heavily depends on the advisor and the research team.

I integrated two different teams (both from the same lab) during my PhD. I don't like remote work so much, so I basically came to the lab every day.

Regarding the first team, we were only two regulars coming to the lab, while all the other researchers were at home. However, almost everybody was there for the second team.

Now you might say that it was during the pandemic, but it remains true even today.

Usually, researchers are pretty open to discussion when you apply for PhD, so this is something you will have to discuss with them to know the habits of the team.
