Sure, find the job/maint plan that runs it and disable that job. CheckDB does not run automatically. There is a job or maintenance plan that runs it.

However, that is really bad practice and not a solution. You need to be running checkDB somehow so that you can detect corruption before it affects the users, before it becomes irreparable.
