Trying to understand my NVR /Camera setup

You just need to update the firmware on your existing NVR.
Hi, I am certainly not disagreeing with you, as I do not know myself. But I have read in quite a few places like Hikvision (sure, it is theie interest for me to buy again), but other sites I have read as well state that going from V3 to V4 could brick the NVR. I do realise you have to do it is stages, but it is a risk right ?

Yes, but only if too big a jump to the V4.x version is attempted.
Hikvision published an advisory how the update should be handled.

Here is Edge in Win10 on a K2-series, almost the same hardware as your I-series NVR, using firmware V4.71.005 build 220524
You can see that Edge is not running in IE-mode either, no plugins.

Attached is the Hikvision advisory on how to safely update to the V4.x firmware that they published after finding that customers had inconsistent configuration databases as a result of too big a jump.
