How do I disable check engine light (P0420) that came after filling up gas tank?

Asked by Zainul on Friday, May 19 2017 for a 2007 Honda Accord V6-3.0L

I filled up gas last night and check engine light came up almost as soon as I start driving. I opened and closed the cap tightly and the light wont go away. Could this really be a Catalytic converter issue?
