You can put it directly on the floor. It has rubber feet right? The only thing to consider is if it vibrates and the two surfaces rattle, so if it's not doing that, you're good. The spikes are for carpet, so no need to put spikes on LVP flooring. You can just use native feet on hard floor like that.
The bigger thing to worry about is the acoustics of the room with no carpet or limited carpet.
Very best,
