Not at all. I have never seen a debit card giving cash redemption.
The only way you can use it is, move to SBI site and redeem these points to pay your CC bill. But remember to divide the points by 4 and pay the same amount to CC because part payments not allowed. So indirectly it is like cash redemption. Visit
https://rewardz.sbi and under recharge/bill payment select all services. There you see option to pay for CC. For other bills you can choose to pay in parts like points and over and above payment via debit card.
