It is possible to update the display every minute, but this display (4.2") with ESPHome doesn't support a partial screen update. That's mean it takes around 5 seconds to fully update the display and I think it's quite annoying to see the display flashing every minute.
If you plan to use ESPHome, recommend you choose another display that supports partial updating, or you might need to write your code from scratch in order to utilize partial update function.
Can you use an e-ink display as a clock?, is it fast enough to refresh every minute?
