Hello hal lavender,
The online help has the data extract and data refresh options listed as well - https://onlinehelp.tableau.com/current/pro/desktop/en-us/help.html#extracting_TDE.html?Highlight=tableau.com
I hope this helps.
Thanks Patrick but I think only the tabadmin commands will do what is wanted
You'll likely use the tabadmin set [option-name value] command most likely.
You can perform certain administrative tasks and change Tableau Server configuration settings using the tabadmin command line tool. It installs with Tableau Server by default and cannot be installed on other computers.
Why do you ask? Like, why would you want to disable caching? What do you mean by "live connection"? Some specifics as to what you want to accomplish would help.
