If you cannot explain the business use, do not assume
Gear, software, a portion of home internet, contractors, and travel to a shoot are the kinds of costs creators ask about. Whether you can deduct them, and how much, is local law. Mixed use (a camera you also take on vacation) is where people get sloppy.
Save the receipt and a note about the job it was for. If a deduction feels like a loophole you saw in a video, that is the one to ask a CPA about before you file it.
