Not sure on the A13 as I don't have one, but if you have the option to Archive apps, it would show up right next to the Uninstall button in the app's info screen. If that option is not available, the only way to do this is to allow the system to handle that itself. Go to Device Care in your Settings, find the Battery section and there go into Background usage limits and either put the app in the Sleeping or Deep Sleeping section (the latter auto-archives apps you don't use for a long time, but re-enables them automatically if you open them again; just bear in mind that if it's been a while, the app may not work until it updates first).
