@HarshaRatnayaka-8891 Thanks for posting in our Q&A.
Based on my experience, audit logs may record some information.

We can refer to the following link to track. I think track device compliance policy is same as the device configuration policy.

Note: Non-Microsoft link, just for the reference.
I have done the test in my lab. I tried to delete a compliance policy in intune portal and I can find a record "Delete DeviceCompliancePolicy" in Tenant admin > Audit logs. When I checked more details, I can get the deleted compliance policy's name.
Then we can try to filter to narrow the scope. Based on my test, we can find the target compliance policy's assignment group name in "Update Assignment DeviceCompliancePolicy".
Hope it will give you some ideas.
