Living with high calcium score

I am a 53 year old male. Just found out I have a CAC of 731. Most of it (699) is in the right coronary. I exercise 5 times a week , used to eat eggs every day (15-20 per week), cottage cheese and yogurt. Upon hearing this news, stopped eating eggs right away. Just trying to figure out what else to adjust. I don't have BP and am at a healthy weight of around 160 lbs for 5'8".
Doctor still has to reach out to me and I think most likely I will be put on Statins. I have high LDL and Apo(b), but triglycerides are under control.
The question I have is, how else should I adjust the lifestyle. I don't drink or smoke or eat meat. Should I reduce how hard I work out? I used to take my HR to 165 and whenever I did it I used to get a heartburn. I was thinking that the workout has triggered acid reflux but looks like something else is going on.
For those with high CAC , how hard do you work out? Should I stop hiking and running? Looking for some insights.
