@Rahul Prabhakar Thank you for reaching out to us, to have adaptive application control what kind of plan do you have enabled within defender for cloud?
As per our documentation - https://learn.microsoft.com/en-us/azure/defender-for-cloud/adaptive-application-controls this feature requires Microsoft Defender for Servers Plan 2.
If you have the above plan, on the workload protection screen, on the right side you will see the option - Enable adaptive application controls (refer below screenshot for reference)
Also, you can refer to this doc - https://learn.microsoft.com/en-us/azure/defender-for-cloud/enable-adaptive-application-controls which would further help.
Let me know if you have any further questions, feel free to post back.
