How to block DNS on PS5 console that has not been jailbroken before? Modded Warfare provided DNSs don’t work

Hi,

I am new to the PS5 JB scene.

I am on PS5 version 12.70 and I followed Modded Warfare's video to prepare for the upcoming JB. https://youtu.be/s7ewxNqcit8?si=L0IeQOX0RUDd_ZYt

To block Sony servers, he provided two manual DNSs, but neither works for me – the console simply connects to the internet without issues.

45.56.67.85

62.210.38.117

Someone suggested setting it up to 127.0.0.1 and then using something called nanodns. I asked if nanodns can be installed on a non-jb console and they told me that it cannot.

So my question is: how do I block updates safely on a non-jb console so I can jb when it's available?

Right now, I have it set to 127.0.0.1 just so that I don't get updated by accident, but it's my understanding that I can't jb without the internet using the webkit exploit.

Thanks in advance.
