There are lots of Zigbee / Zwave fan motor control switches available.
The 3 way would be an additional same technology switch that is linked to the fan switch.
First: choose Zigbee OR Zwave for your overall system. Then pick a brand. Then buy and install the fan switch. Then program it.
Is there an existing mechanical switch for that same fan? Is there an existing 3 way mechanical switch too? The smartswitches would just replace them if so. What wiring is there - black / white / red? Does the fan have speed / reverse control? That gets more challenging to get a correct smartswitch.
