Without a doubt, you can. There may be a few different actions that are related to double-tapping on the AirPods. On your iPhone, choose Bluetooth from the "Settings" menu to accomplish this. From the list of devices that are present at that time, choose your AirPods. Select the two-tap configuration next, and after that choose the tasks you want to control with each. The two-finger tap can also be used to skip tracks, activate Siri, and play/pause music. If twofold tapping is something you could live without, you can completely disable it.
