The newest Roku Ultra 4850 supports wifi6(ax) and WPA3. https://www.roku.com/products/roku-ultra
The newer Roku-branded RokuTVs (Pro and Plus series) are also wifi6(ax) so also support WPA3. (only applies to Roku-branded RokuTVs currently, as opposed to RokuTVs made by other television manufacturers). https://www.roku.com/products/roku-tv
A device needs wifi6(ax) capability in order to use the WPA3 security protocol.
