Whenever I want something taken off calendar, I call the judge's clerk (the clerk who sits in the judge's courtroom -- not the clerk at the civil case window) and say, "I'm [myname], attorney for [plaintiff]. There is a default hearing set for [time] tomorrow before judge [judge's name], and I need it taken off calender, because [reason, e.g., plaintiff is ill; defendant has proposed a settlement; I have a conflicting hearing unexpectedly ordered by judge somebody else, etc.]. And, the clerk says, "Okay," and that's the end of the matter.
It's always possible that because you're not a lawyer, that the clerk will tell you that if you don't show, the court will order you to pay sanctions for wasting the court's time. But, I doubt it. Ultimately, if you don't show up, and there's no defendant, then the court will just take the matter off calender. But, if you don't call and try to have the hearing cancelled, and the judge gets annoyed, you could find yourself being called in to explain yourself, and that could lead to a sanction. So, don't just be a no-show, and give the judge a reason to be pissed off.
Note: I see you are asking a lot of questions about independent contractor agreements and they seem to shift back and forth between California and NY as jurisdiction. If these questions are about work done by you while located in California, then it's very possible that every single answer you have previously received is wrong. California employment law issues are supposed to be sent to a specific category where only California employment law attorneys can answer. If your issue actually concerns California law, and you would like me to reconsider all of the relevant issues, then please post it in the California Employment Law category and put my userid ("To socrateaser") at the beginning of your question.
Hope this helps.
