Many? In 92? I don’t think so. AitD was the first in my (admittedly non-comprehensive) experience. 92 was full of sprite-based pixel art adventures, to be sure.
Relentless/Twinsens was 94. RE and FF7 were years after that
Spaceship Warlock did it in 1991 but was a Mac game so it went deeply under-appreciated. Admittedly this might fall outside your definition depending on if the focus is “3D scenes rendered to 2D” or “pretending they’re full 3D with a handful of actual 3D characters on top.”
LBA1 uses Gouraud shaded polygonal characters on top of tile-based 2D backgrounds. LBA2 does the same for indoor areas. For outdoor areas it uses a technique I don't recall seeing in any other game: every time the camera changes position it renders detailed and fully textured 3D scenes to a static background buffer (possibly taking a few hundred milliseconds), then renders the characters on top of that background. The camera changed position automatically, and you could also press a key to force it to re-render the background if you wanted a different camera position. It's a good compromise between real-time and pre-rendered IMO.
