All of that is pretty new and would be considered top end right now! The only screens which come close to meeting the required specs are the Asus PG27UQ and Acer X27 really. If I assume by HDR you mean decent high end and meaningful HDR
there’s no 32” options yet as you say, although Philips announced the first option recently which has most of these specs minus traditional Gsync module. Although it will support Gsync VRR to some extent (TBC whether certified as Gsync compatible or not) via adaptive sync anyway. Not sure if you were specifically after hardware Gsync or not..

Given that’s announced I would be very surprised to not see gaming models announced from Acer and Asus in the near future with 31.5” screen, IPS panel, 120/144Hz and adaptive sync of some variety
You’ve got more chance of them coming in at your desired price range if they are non hardware Gsync as the v2 module needed for 4K at 144Hz is very expensive. Also more chance if it’s a lower end HDR without FALD as again they are very expensive (and also currently linked to Gsync v2 module anyway)
