ENABLE_ACCOUNT_DELETION feature does not work

[vunguyen-dmt]

I am using Tutor v14.0.1.
I created a plugin to disable account deletion but it didn't work.
I 've tried:
(
"openedx-lms-common-settings",
"FEATURES['ENABLE_ACCOUNT_DELETION'] = False"
)
AND
(
"openedx-common-settings",
"FEATURES['ENABLE_ACCOUNT_DELETION'] = False"
)
