The question

If I, the principal applicant who is on F1 , switch to Adjustment of Status (AOS) in the U.S. under EB2, can my spouse(derivative beneficiary), who is abroad and already listed on an approved I-140 with an assigned NVC case number, proceed with consular processing simultaneously ? Currently, the NVC has not sent any consular processing instructions, and I haven't notified them yet. Is it possible for me to simply notify the NVC that the derivative beneficiary will continue with consular processing, and will the NVC allow it?
