Hello Gowri,
I don’t believe it is possible to run a cron from within VTEX. The closest thing that would fit is this response from George on another topic, which is in portuguese:
Translating it for you, the topic was about Master Data triggers and his recommendation in that case was implementing an external cron and have that point to VTEX either through one of our API endpoints or through a VTEX IO Service. Then whichever process you need could be done internally afterwards.
