Thanks for the link.
I was aware of the first group.
This seems to require the setting of a switch to get the appropriate level of VR correction on or off a tripod - though I have never owned any of the 3 lenses.
I was aware of the second group of 3 where the switching is automatic.
The technology seems to go back to at least 2004 when I bought the 200–400.
For the third group I was
not aware of the detail of the enhanced VR detecting ability specifically relating to tripod use.
It seems not to be mentioned in any relevant lens instructions.
Even so many will be aware of the comment in the instructions that on a tripod, VR on is normally recommended with these lenses.
I can confirm the enhanced detail is not mentioned in the instructions for the 180–400 or 500 f 5.6 that I still own.
From memory it was not mentioned in the instructions for the 70–200 FL, the 200–500 or the 300 PF when I owned them.
I have not owned the other lenses in this third group.
Nikon may have been selling themselves short by not providing the detail of how "advanced VR" works in the Group 3 lens instruction manuals.
This leaves 3
possible questions
1/ does Nikon IBIS automatically detect if being used on a tripod?
2/ does Nikon Z lens in lens VR (on most lenses that have it) automatically detect if being used on a tripod?
3/ if yes to 2/ do all Z in lens VR lenses including perhaps the 24-200 have it?
Conjecture implies some shutter vibration and no mirror vibration to consider with the Z6 and Z7series plus Zf a Z6 III
when using the mechanical shutter and no shutter issue with the Z8 or Z9 shutterless operation.
