I've had fewer problems with this than I expected. I think it's because I took pains to make a mental work/life divide a few years ago. The switch for me, whether working in the office or from home, is my work computer. In the office, the ritual start of the day for me was turning on my monitors and logging in for the first time. At home, it's connecting to the vpn, starting my remote desktop client, and connecting. End of the day is locking the screen and turning off the monitors in the office, or closing down the remote desktop client and vpn at home.
Just clicking the close button on the remote window and then disconnecting the VPN is enough for me to feel that it's the actual end of the day. Also, I've made it clear over the years that I don't monitor my work email or Teams chats when off the clock. That helps. Coworkers know that if there is an emergency I will respond to a text or a phone call but an email or a Teams message will go unseen until I login again.
