Z Coordinate Restoration Override?

In the 3.1.0 Changelog, it says in upgrades that "after a tool change, the user Z coordinate is restored immediately instead of by the end of the next G0 or G1 command." Does anyone know of a way to override this?
I have 3 tools that I want to find Z offsets for, relative to T0. I'm currently trying to perform a Z probe (underbed piezo), set that location as my new Z = 0, then switch the tool and probe again. However, G30 S-2 causes the tool to slam down into the bed after I call for a tool switch (this doesn't happen with G30 S-1)
I think it's because of the Z coordinate restoration. The probe normally triggers at around Z = 25 so when G30 S-2 sets that location to Z = 0 and I try to perform a tool switch, it seems like the printer is trying to move down to "find" the original Z = 25 value even though it starts out at a lower value already so it can never find that position.
Does anyone have any suggestions on how I can remove the Z restoration feature without reverting my firmware back to an older version? Alternatively, does anyone have a more efficient way of finding Z offsets for multiple tools with a piezo on a moving bed? Thanks!
