Hello Prabhu,
One way is to set the execution of the Scheduled event for example every hour and then create some logic within your scheduled event microflow with a decision wether or not to execute the full flow or not.
You can for example make an entity with one object with the settings when it needs to be executed or not.
Hope this helps,
Good luck
I am btw curious of other options what other people prefer to use
Explanation:
You create an SE that goes off more frequently than you want for example every minute:
Then create your set up like this
Then add in SE_Decision your logic that you want for example a boolean that sign if the funcitonality is enabled:
Please be also aware to clean up your scheduled events that are executed within mendix everytime a SE is executed a record is created:
see alos the documentation:

Good luck
Hope this helps
