My take is that it's about the "stimulating activity" rather than the actual screen time. When broken down it's intuitive, but the "reduce screen time" adage often gets repeated without that distinction.
Specifically about your problem: for me, I move from a state of "active engagement" to "passive consumption". 1 to 2 hours before bed, I stop doing anything engaging that requires my active participation - work, video games, learning. I shift to lounging on the couch and reading fiction or watching a movie/show. The key is in my intentions behind each: in the evening, my goal is to relax. I dont turn on a movie with the intention to learn or to be entertained; I'm just there to experience it.
Sorry if that's too abstract; the feeling is hard to communicate. Hopefully it's a useful starting point for further thinking.
