Are there quieter blades for the Mavic Air 2 that don’t break warranty or TOS? I do apologize if this has been asked numerous times. The search feature didn’t really help that much plus some of the posts used acronyms that I’m unfamiliar with. I need quieter blades so I can check my uncles farm and don’t want to spook the cows and start a stampede. Thanks in advance for all answers.
