Yes, under Linux, the 2.5 Gbit/s network chip usually works in current kernel versions without an additional driver; according to the Gentoo Wiki, it runs with the r8169 module and is supported with appropriate firmware from kernel 5.9 onwards.

If you are using an older kernel, a manual Realtek driver may be necessary. The ASUS specification names the controller as Realtek RTL8125B 2.5Gb Ethernet.
