You can try this:

.
.
.

import { useBackHandler } from '@react-native-community/hooks'

.
.
.

useBackHandler(() => {
    //your function
    Alert.alert('Teste')
    
    // Return True will remove BackPress Event, if you set False it will allow it to run your function but will have the BackPress Event anyway.
    return true
  })
