Can I install NextCloud on Buffalo’s NAS?

I am looking into buying the “BUFFALO TeraStation 3420DN” because of the amazing security features and can’t seem to find anything written or any video made on wether or not you can use NextCloud with this NAS.

I am looking for a NAS that is encrypted at rest and offers end-to-end encryption when using it.

Basically the more secure the better, which is why the BUFFALO TeraStation 3420DN Intrigues me so much.
