I don’t know if this is an automatic setting in new installations, but it never used to be and isn’t on my installation.

You should be able to remove it from the Mail Shield settings, see attached image, click to expand.
Menu > Settings > Protection > Core Shields > Mail Shield > Add a signature, etc.

Yes, setting the signature in emails is an automatic setting.
