Hey Sri,
You can use a certification exclusion rule to remove specific entitlements from the certification all together:
Do you want the entitlements still in the certification just not revoked if they’re denied? If so, what did you want to happen to them?
You could also use a before provisioning rule: Exclude specific entitlements from auto revocation to check if the provisioning plan is coming from a certification and if the entitlement is in your “do not revoke” list. If so, remove it from the plan so it is not deprovisioned, even if the reviewer selected “Revoke.”
