You cannot drive without a license on the road. You either need to have an interim driving license or original driving license. However, these days, and there is no option to apply for Interim driving license via NTSA TIMS portal.
The best option available is to apply for the old driving license (which lasts for one year) via eCitizen as you wait for Smart DL.
Smart DL takes 3 to 4 weeks after taking your Biometrics before it is ready for collection.
