You could put more soil on top but you will still need to trim. Plus fresh Amazonia will give you a little NH3 spike which your livestock probably won't like.
Pretty much this.

But, as long as your HC is growing well and sending out deep roots it won't come up. I had my 20L ~80% carpeted with HC at one point and never had issues with it lifting up. All I had to do was keep it trimmed and it was happy. Every 2 weeks seemed to be the regular.
