1.17.1 only culling certain faces

[KaboomRoads]

how can i make a block only cull the face of the block below it instead of either culling all faces or no faces

similarly to the culling an enchanting table but i cant find anything in the existing classes

i have 2 voxel shapes but only getShape affects the occlusion. i need it to stay a full 16 by 16 by 16 cube though but that makes it occlude every side

@Override
	public VoxelShape getShape(BlockState state, BlockGetter worldIn, BlockPos pos, CollisionContext context) {
		return SHAPE;
	}

	@Override
	public VoxelShape getCollisionShape(BlockState state, BlockGetter worldIn, BlockPos pos, CollisionContext context) {
		return COLLISION_SHAPE;
	}

how can i only cull one particular face when my block is next to another block

in this case i want only the top of the block below my block to be cullable and by that i mean i only want the bottom of my block to occlude

i want it to occlude similarly to slabs

my block culls the faces that are next to a block fine but if its next to itself it doesnt work because it has noOcclusion

also because it has noOcclusion it doesnt occlude the block beneath it

but if i remove noOcclusion it culls all faces next to it causing xray

the voxel shape causes this but i need the foxel shape to stay the same so that the block outline is a full block but the block collision is a half block

the only thing i could do so far is change the voxel shape to a slab shape or anything that isnt a full block but then the block outline is smaller and i need it to be a full block shape

as long as the block shape is a full block it occludes everything but if its only a full block side on one side it doesnt

i tried looking through most of the existing block classes and also model json files and i cant find anything that solves this problem there
