Welcome to the Wyze User Community Forum @kshahar! 
Glad to have you aboard! 
If you enable the VOIP setting in Account → Notifications → Push Notifications, your doorbell will place a video call to your phone instead of getting a standard push notification when someone rings the bell. You can then assign a custom ringtone to your doorbell in your Android settings. Motion and AI videos will still be by push notification.
Alternatively, since you do use Android, you can use a 3rd party app like MacroDroid or BuzzKill to set custom notification tones. See this post for a detailed description.
