How to unlink my phisical headphone mute button from the teams digital unmute button ?

my school started using teams for work and classes, but there is a problem. I have to talk with my study group of five people in discord, but my physical unmute button linked with Microsoft teams meaning I can't talk with my study group. If I try to unmute with the physical button it unmutes me in teams. Please tell me how to turn off this feature.
