Don't think so. No one has mentioned even the "latest and greatest" Orbi firmware supporting WPA3, whereas page 71 of the "AX" Orbi clearly offers WPA3 Personal as an option, along with a warning:
Some older computers and WiFi devices cannot use WPA3 or WPA2. If your network includes old computers and WiFi devices, select the WPA-PSK[TKIP]+WPA2-PSK[AES] radio button.
The security setting applies to ALL WiFi devices. My guess is that switching to WPA3 means that immediately every smart plug, security camera, television, and most laptops and smartphones in the house will be cut off.
