That would certainly work 😊. I like to keep it in HV until the distance to home is about the same as my remaining EV miles, then switch to EV mode.
Switch earlier to EV mode if you're above your home elevation. I switched to EV mode last summer with 80 miles left and thought I had waited too long. Granted, I had a 4,300 ft drop from where I was to home, but between regenerative and blended braking the car stretched the estimated 20 miles of EV range out to a point where it finally ran out of battery about a quarter mile from my home.
