Switch off headphone notifications on mac OS 11.1

Hi all,

I have bluetooth headphones (Powerbeats Pro) and they are connected with my iPhone, iPad, Apple Watch and MacBook. Now when I use them with my iPad, I keep getting notifications on my MacBook that I can connect, even if I don't want. Is there a way to make those notifications disappear, except for unpairing the headphones from the MacBook which is annoying?

Thanks for your help!
