I want to use IPTV and wired Internet at the same time by connecting a switching hub to the Deco X20 router.

I plan to use IPTV by connecting an Internet connection LAN cable to one port on the back of the TP-LInk Deco router and a switching hub to the other port to expand the port.

I understand that the IPTV function can be used on one of the two ports through the TP-Link Deco app.
If I enable the IPTV function on one port and connect a switching hub to this port, can I use IPTV and wired Internet at the same time?
