WW,
You can totally make progress. In the meantime, get yourself some OLY shoes for squatting. And don’t sweat it.
You’ve built those calves to be badass! It will take a minute to rewire/lengthen that system. This is ok.
Muscles and tissues are like obedient dogs.

Def spend a little time each day working on them. My wife Juliet it the same. She was a toe walker because of her incomplete hip extension. I’m sure you are the same. Open that hip up in extension. Load that ankle in a systems approach way (hint not just rolling…). Even 5 degrees of change will improve your life.
