I Have Been Diagnosed With Hypertrophic Obstructive Cardiomyopathy. I'm On

I have been diagnosed with Hypertrophic Obstructive Cardiomyopathy. I'm on 25 MG of Metoprolol Tartrate twice a day. I've been seen by electrophysiologists, had a heart MRI, echocardiograms, stress tests, etc. It's been suggested by two of the 3 electrophysiologists that an defib might be the way to go however another electrophysiologist doesn't agree that it's necessary at this time. I'm 62, 5'9", 157lbs and in good health. My question: I LOVE hot yoga but my doctors have advised against it. I wondered if I could do it 2-3 times a week in the early morning when the heat is not as high. What do you think?
