Process for Physical Delivery in F&O

What if I do not have sufficient obligation in the form of Shares/ Funds required to meet at expiry for Physical settlement of the opted positions?

If you do not maintain sufficient free shares/ funds to meet the expected delivery obligation that is required for the Physical settlement in the contract in which you wish to take Physical delivery then that contract will be squared off in the End of Settlement process which is run before the expiry and positions will not remain open for delivery settlement.
