Remove Backup and Factory reset option from Settings app

I want to remove some features from my settings app (device is rooted)

I used adb shell pm disable 'com.android.settings/.Settings\$SecuritySettingsActivity' to disable security settings and it worked. However, I am unable to find the activity name to disable backup and factory reset option.

Here is the AndroidManifest.xml of the settings.apk (I'm using LineageOS)

So far I have tried

adb shell pm disable 'com.android.settings/.BackupSettingsActivity'

and

adb shell pm disable 'com.android.settings/.Settings\$PrivacySettingsActivity'

Both of which did absolutely nothing. I am still able to open backup and reset option from settings.

When I try to launch the said activities

adb shell am start -n com.android.settings/.BackupSettingsActivity

It errors out at saying BAD COMPONENT

while these two commands open the back and reset activity that I want to disable

adb shell am start -a android.settings.BACKUP_AND_RESET_SETTINGS

adb shell am start -S 'com.android.settings/.Settings\$PrivacySettingsActivity'
