[1.19.4] manipulate the FallingBlockEntity to not fall but displace horizontally

im updating the manhole block to 19.4 im looking for a way to make the cover animation smooth 
 

	FallingBlockEntity fallingBlock = FallingBlockEntity.fall(level, pos.north().above(2), BlockInit.MANHOLE_COVER_PANEL.get().defaultBlockState().setValue(BlockStateProperties.FACING, Direction.DOWN));
	level.addFreshEntity(fallingBlock);
	

the basic code for the falling block just create an entity whit the block model and let it fall from the starting position 
i need to move horizontally so i set a delta 

	FallingBlockEntity fallingBlock = FallingBlockEntity.fall(level, pos.north().above(2), BlockInit.MANHOLE_COVER_PANEL.get().defaultBlockState().setValue(BlockStateProperties.FACING, Direction.DOWN));
//fallingBlock.set(fallingBlock.DATA_NO_GRAVITY, true);
fallingBlock.setDeltaMovement(0.1D, 0.4D, 0.0D);
level.addFreshEntity(fallingBlock);
	

soo it posible to set the FallingBlockEntity to move other way besides down ??

the other thing i was thinking was to make a custom FloathingBlockEntity  
but the old problem affect me like wheres the FallingBlockEntity renderer and model classes to extend the call and use the same renderer not having to manually create a model of the already existing manhole_cover_panel block 
 

Thanks for your time
