How can I prevent my Garmin workout to adjust music volume?

Today I noticed the while in a planned workout on my forerunner 970, each time I get a notification that I am offtrack or not within the expected pace, my music volume gets overridden to it's maximum. 

Is there a way to prevent overriding the music volume while I am on a workout?

It was bad, I had to take my headphones out and start listening to my music on the watch speakers, but even so, the music was too loud and I could not controlled myself. Each time I reduced the volume , when I get a workout notification alert , it gets overridden again.

I wasn't able to find a way to adjust this setting.

Help!
