Inky WHAT refresh part of the screen

Hi all

I have seen a bunch of questions on this topic with no resolution, but they were a couple years ago, so I figured I’d try and see if anyone has any new ideas.
My issue is that I am trying to make a clock with my inky WHAT screen, which I have already coded up with some weather information etc.
The problem comes when I am refreshing the screen every minute to update the clock. As you guys know, the refresh on the screen makes the whole thing flash for 15 seconds or so, making it basically useless for a clock.
I know I should probably get an LCD screen or a small OLED screen for this, but I was hoping to use e-ink if possible.
Does anyone know if it is possible to just refresh part of the screen without having to wipe everything out?
