Can the following be achieved via configuration of control variables in the out-of-the-box Lifecycle Manager...

Yes. Policy checking behavior is one of the areas commonly controlled in LCM request workflows through workflow variables or configuration controlling policy evaluation mode. IdentityIQ can evaluate whether a requested access change would violate configured policies before the request is finalized or provisioned. Depending on configuration, the system can present policy violations to the requester, block submission, continue with warnings, or require additional approval/mitigation. The proposed behavior — checking whether an access request would violate policies and letting the requester review before submitting — aligns with interactive policy-checking behavior in LCM. This is an execution behavior of the request workflow, not an application schema setting. The engineer must still ensure policies are configured and enabled, but the workflow/control-variable layer can determine how those checks are applied during request submission.
