Forget old wifi credentials

Hi folks, I used Al Azifs exploit method to run HEN on my PS4 and got it cached so that I can use this offline.

However I would like to use an ESP2866 to load the payloads from there.

Can I somehow remove the old wifi credentials from my normal internet connection on the PS4?

I am afraid that the device will fallback to my normal internet connection if the ESP2866 should be damaged or if I forgot to plug in etc.

Thank you for your advice.
