Short answer: you cannot.

Panic is a sudden sensation of fear, which is so strong as to dominate or prevent reason and logical thinking, replacing it with overwhelming feelings of anxiety and frantic agitation consistent with an animalistic fight-or-flight reaction. (Source)

When a human or animal is in panic, the higher brain functions (like reasonging and logical thinking, but also the ability to analyze a situation and learn from it) are deactivated. If you want to train your dog, you must do that when she's not panicked.

What you want to do is a desensitization training and counter-conditioning. You'll find many instructions online. The ones I find to be most useful are:

• Treating Fear of Storms and Fireworks in Dogs by VCA (written instructions)
• Fireworks Desensitization for Dogs by Trudog (includes several video instructions). Since the first one uses a metal bowl to create loud noise, it's very suited to be used during walks.

To summarize desensitization:

• It's important that you always train when your dog is calm and that the training doesn't trigger the panic (because her brain cannot learn when panicked).
• Use very special treats with a strong smell for the training. Your dog only ever gets those special treats during training, never outside of it. Those treats can be pieces of cheese, hotdog, raw steak (unseasoned) or onything else your dog absolutely loves.
• Start the training with a loud noise that doesn't make her panic. If she shows fear, the noise is too loud and you need to start with a lower volume.
• Create the noise (by dropping a metal bowl or playing fireworks sounds on your phone on low volume) and if she doesn't show fear, reward her with very special treats.
• First train at home, where she has fewer problems. After a minimum of 1 week of training, if she reacts positively to the training, you can start doing the same training during a walk.
• Take it slow! Such a training will take several weeks, probably months. If you go too fast and make her too uncomfortable, you can even worsen the situation and increase her panic.

Such a training can help your dog lose her fear, but if you're too impatient, you can make it even worse. Don't forget that you can always get professional help from a professional trainer. For desensitization training, you would usually have one training lesson every week or 2 weeks where you both review the progress you've made and the trainer gives you more instructions for the following week or 2. The rest of the training you do at home according to the instructions of the trainer.
