Introduction
A mod_security rule may be impacting a user and you want to only disable the rule for that user.
Procedure
User level Apache include files used on a cPanel server can be used.
If the user, for example, is doggie then
mkdir -p /etc/apache2/conf.d/userdata/std/2_4/doggie /etc/apache2/conf.d/userdata/ssl/2_4/doggie
and then create conf files with whatever name is desired but for example in this case
/etc/apache2/conf.d/userdata/std/2_4/doggie/modsec.conf
/etc/apache2/conf.d/userdata/ssl/2_4/doggie/modsec.conf
with the following contents with the rule ID needed.
<LocationMatch .*>
SecRuleRemoveById 930110
</LocationMatch>
and then rebuild httpd.conf and restart the webserver with
/scripts/rebuildhttpdconf
/scripts/restartsrv_httpd --hard
