My suggestion would be to just make sure you have fully configured WordFence to protect the site and leave everything else as is.
Hope this helps.

Please do not. It doesn’t do anything and can easily make your site unsupportable.
If you are concerned about brute force login attempts then consider addressing that with a plugin or add 2FA to your login also with a plugin.
