Work remote (if you aren’t already). I’ve been doing it at various companies for the better part of a decade and rarely work a full 5 days per week. There are probably 4-6 days/month there just isn’t much on my plate that day so I take care of errands or spend time with my family, or just do nothing.
I also work just as hard as I did when I commuted and have never been reprimanded for not getting enough done, quite they opposite in fact.
