Hello Prajwal,
I am afraid you can't. In order to write KCET, you will have to qualify your 10+2 intermediary exams. KCET requires you to have a minimum 45% marks in your +2 examination for you to be eligible to write the test. They do not accept KSOU candidates either. You can learn more about KCET eligibility here : https://www.google.com/amp/s/engineering.careers360.com/articles/kcet-eligibility-criteria/amp
Hope this helps.
