How to make Siri on AppleWatch not connect to my AirPods and not interrupt my music playing?

Question

Who didn't get it from title, here's my case:

I often setup timers and add items to my reminder list using Siri on my AppleWatch. But I also often listen to music (from AirPods, using my iPhone). But each time I use Siri on my AppleWatch, - it interrupts my music to handle the request using AirPods mic... Instead of using built-in AppleWatch mic :\

When timer initiates vibrations, - it also stops music :\

I haven't found anything related in settings. Is it possible to overcome these interrupts? I don't like my music being interrupted.
