The Roon Labs list of officially-supported NUC devices only has Intel products currently. It’s probable that Asus models will be added over time, but Roon Labs never pre-announce things like this.
It’s also highly probable that ROCK will work on the NUC 12 and NUC 13 range of Asus NUCs, but unless they appear on the Roon Labs list, they will not be officially supported.
