If you disable the triggers, the price rules and QCP plugin will no longer execute, until you re-enable them.

This is true when using SBQQ.TriggerControl.disable() (programmatic approach) or when disabling triggers in the package settings (manual approach).

It is recommended, after loading Quote, Quote Line Group, and Quote Line data with the data loader, to force loaded quotes to recalculate after you re-enable the triggers. This is done easily by running another UPDATE batch on loaded quotes and modifying a field that is in the Calculating Fields fieldset on the Quote object.
