How do you manually disable a third-party (non-system) app in One UI on the Note9?

I like to have some apps pre-installed in case of an emergency (e.g. roadside service), but I don't want them to be able to run and waste battery when they are not needed. Normally, I would install the apps and then Disable them under Apps->App Info. However, with the Android 9 Pie One UI update on my Note9, the option to manually disable apps that are not pre-installed has disappeared. According to Samsung Twitter Support, third-party apps cannot be disabled. Which is not entirely correct, since there is an option under Battery->Settings to "Auto disable unused apps". Unfortunately, this option is NOT disabling the unused apps.

How do you manually disable an app you have installed under Android 9 Pie One UI???
