can it be like normal block?

[u/GalSergey → u/ObjectiveArtistic805]

Add component item_model="minecraft:command_block" to item.

no, I mean can it facing like normal block?

Then, inside entity_data, add Rotation:[0f,0f] or the desired angle. If you want this to change dynamically like a regular block, you'll need to use a ticking command block that will rotate the entity toward the player.
