Hide validation errors for security reasons

[sinmax01]

For security reasons (pen test), we would like to be able to remove any validation error messages (The field aaa does not exist on the type bbb.) in production environment. So just specify something like "Invalid query".
Is there a workaround for this?
AddErrorFilter() and .ModifyRequestOptions(options => options.IncludeExceptionDetails = false)
does not work for validation error (do not catch this type of errors).
