Hi @Ratna Choudhury ,
Since you tagged Azure Security Center, I assume you are referring to the Azure Security Center Security Control, Encrypt data in transit.
If you have limited permissions on your school account, you can always create a new tenant for testing purposes.
You could use either the Azure Security Center Free tier or enable the 30-day trial of Azure Defender.
If there are any specific questions about costs, you can reach out to Billing support to get clarity around this.

Let me know if this helps at all!
