Turn off notifications for 1 of 2 accounts

I am signed in with two accounts in the instagram app. My private account, and a second one which I sometimes share my hobby on. I am way less active with the second one and I don't want push notifications for that specific account, so I tried deactivating notifications in the instagram app, but I still get tons of really annoying "x posted y". I don't want to deactivate notifications altogether in the android app settings because i still want to receive notifications for my first account. Is that possible at all?

System Configuration: Android / Chrome 94.0.4606.85
