Select/Change Table are mapped from the ticket type settings;
If you unmap you will need to recreate the flow manually with an automation command.
You would need to make a dummy entity type, make a custom entity screen, make a table entity grid on it, then setup the automation from that grid.
Something like if ticket has no entity then set entity with selected, - if already has table entity set ask for pin before changing.
As said its not going to be a simple tick box to enable
