Default "Enabled features" for newly created Virtual Servers?

Where can I change these default enabled features for a new virtual servers that appear on the “Enabled features” section of “Create Virtual Server” dialogue? For example if I want all mail-related and awstats checkboxes to be turned off by default to not to turn them off every time manually?

Most default enabled options when creating new virtual servers will be found in Server Templates->Default (or whichever server template you want to modify). Some limits-related options are in Account Plans.
