About 3BM31 APFSDS/APDS for 2S14 ZHalo-S

Many of you heard about the only soviet wheeled tank hunter, 2S14. And I’m quite interested in it too, here is the information about it from the old forum.
2S14 ZHalo-S (BTR-70 TD)

I noticed that someone mentioned about a APFSDS/APDS called 3BM31, but I can’t find any detail about it, so here I want some help before I move the old suggestion to the new forum.

But I think this is not enough, the source also suggested that the drawings are probably not accurate.
