I already applied for visitor visa; can I apply for the DV Lottery?

I have already applied for a visitor visa to USA. I was born in a DV Lottery eligible country. I have the required education too. Can I apply for the DV Lottery?
According to the DV Lottery instruction, "persons who are already registered for an immigrant visa in another category may apply for the diversity visa program."

If you have all the eligibility you can apply for the diversity visa lottery each year. Applying for the DV Lottery doesn’t be confused with the other visas according to the State Department. After winning the lottery only you will be asked to apply for an immigrant visa. Even when you are staying legally in the USA, you can apply for this program. If you won the lottery while you are staying in the USA legally, you may contact the USICS office to change your status to LPR. This procedure should be done before the 30th September as after this date the winning of DV Lottery is not valid for a diversity visa or change of status according to the lottery law.

The EDV is a free to apply lottery although the winner is not given a visa directly, but he will be allowed to apply for immigrant visa and the applicant must pay non refundable visa fees and all the related fees by himself.
