How to disable apache modules?

Hi,
I am using WHM, cpanel and I rebuilt apache using easyapache.
I also have root and ssh access.

I have these apache modules :

 
    [0] => core
    [1] => mod_authn_file
    [2] => mod_authn_default
    [3] => mod_authz_host
    [4] => mod_authz_groupfile
    [5] => mod_authz_user
    [6] => mod_authz_default
    [7] => mod_auth_basic
    [8] => mod_include
    [9] => mod_filter
    [10] => mod_deflate
    [11] => mod_log_config
    [12] => mod_logio
    [13] => mod_expires
    [14] => mod_headers
    [15] => mod_setenvif
    [16] => mod_proxy
    [17] => mod_proxy_connect
    [18] => mod_proxy_ftp
    [19] => mod_proxy_http
    [20] => mod_proxy_scgi
    [21] => mod_proxy_ajp
    [22] => mod_proxy_balancer
    [23] => mod_ssl
    [24] => prefork
    [25] => http_core
    [26] => mod_mime
    [27] => mod_status
    [28] => mod_autoindex
    [29] => mod_info
    [30] => mod_suexec
    [31] => mod_cgi
    [32] => mod_negotiation
    [33] => mod_dir
    [34] => mod_actions
    [35] => mod_userdir
    [36] => mod_alias
    [37] => mod_rewrite
    [38] => mod_so
    [39] => mod_php5

Code (markup):

I read somewhere that we should disable unneeded modules to save memory.

Can you please inform me what modules are not necessary generally and how to disable them ?

I never use cgi scripts.
So, can I disable mod_cgi ?


I also want to disable mod_userdir, mod_actions etc to save memory.
I have looked into my httpd.conf file, but there is no mention of these modules.

I think, there is no option to disable these modules in easyapache also.

How to disable them?
Thank you
