How can I execute a Simulink block only when a specific condition is met?

Hi all,
Is there a way to execute the following block diagram only when a certain condition is satisfied (e.g., when a joystick button input is detected)?

Hi 준호,
To execute the set of blocks conditionally place them inside a subsystem. To do so select all the blocks then right click and select ‘Create Subsystem from Selection’. This subsystem can now be executed conditionally using conditional blocks like ‘If Block’.
The setup can look something like this:
There is also a pre-existing ‘If Action Subsystem’ block that can be used.
Alternatively, the conditional If block can also be placed directly before a desired block without creating a subsystem.
Here is the documentation link to subsystem and conditional blocks:
Hope it helps.
