If you are using Android Pie, then go to "Phone", then press on the vertical three dot symbol at the top right, choose "settings" then "Record calls" and turn off "Auto record calls".
Honestly Google Assistant is much better than Bixby. You can do that through Google Assistant by saying for example" Ok Google, naviagte to home" and it will work fine!
Launch Bixby voice by pressing the Bixby key, then click on the 3 dot symbol on the right then press settings, and from the menu choose the "Voice wake-up" and turn it off as attached.
Ah I see, now I understand what you have meant to do. Using Android Pie, I can go to setting, Advanced features, smart pop-up view and then turn off all the apps as attached. Hope this helps!Regards,
