What is the current way to isolate the battery?

On Step 25 of the iPad Pro 10.5" Battery Replacement Guide, it says,

The battery isolation pick or battery blocker is an outdated way of isolating the battery, as you risk damaging the battery pins underneath the logic board.

However, it doesn’t say what the not outdated way to isolate the battery is. So what is that?

Edit: Can @schnabel address this?
Edit 2: I just noticed this response to this issue at the end of the Guide:

We are currently still researching a more reliable alternative to the battery isolation procedure. As of now, the battery blocker method still works—it just has substantial dangers. This is especially true for iPad Pros, where the Logic Board is adhered to the frame. I’ve reworded the warnings to reflect this.

So @arthurshi: Is there any update to this issue? I need to replace my battery ASAP; what tool should I use?
