You can't because your computer might crash if you push on 32bit, This game development is intended for stressing the GPU more on RTX GPUs so if your desktop or laptop doesn't have RTX Graphics then don't bother trying.
Thats bs, the game doesn't even use raytracing, its using baked lights. But yeah, 32-bit computers are heavily under powered so its not gonna work - but you dont need a RTX
