The current models of iPad Pro support connection of one external monitor via USB-C (using DP or HDMI Alt Mode) or a an appropriate HDMI or VGA Adapter. That said, for these models of iPad, iPadOS17 also supports simultaneous mirroring of the iPad Pro screen to an AppleTV or compatible Smart TV using AirPlay.
As such, using both a direct wired connection to an external monitor and AirPlay, it is possible to use two external displays. However, you must recognise that when using this arrangement, AirPlay can only mirror the iPad display; effectively, you still have only two displays.
