Hide Error Page Signature

Hi, is it possible to hide the error code signature, without seting up a custom error page?

Dont wanna see “Proudly powered by LiteSpeed Web Server
Please be advised that LiteSpeed Technologies Inc. is not a web hosting company and, as such, has no control over content found on this site.”

In my view kinda security question…
