If switch supports Deco Ethernet backhaul protocol, you can connect them directly to the switch. More on that topic is here: General questions about Ethernet Backhaul feature on your Deco
For that to work, you will also need to configure Deco mesh run in Access Point mode, by default it runs in Router mode. This is how you make that configuration change: Switching a Deco to Access Point (AP) Mode
With Deco mesh running in Access Point mode, you can hard wire Deco nodes to any available Ethernet port on your network: switch, each other, and that also includes TP-Link Archer AX72 Ethernet ports.
You can for example hard wire all of them the following way:
I suggest you choose Deco X50-POE for your Deco mesh. This Deco model is designed to be ceiling and wall mounted. It is also POE, which may let you utilize POE capabilities of your switch.
Note that Deco mesh runs its own WiFi network independent of TP-Link Archer AX72. It is recommended to turn off WiFi on router and let Deco mesh provide WiFi coverage at your place.
If you find that WiFi coverage near router is not up to your needs, get one more Deco unit and hard wire it to TP-Link Archer AX72 with short Ethernet cable. That unit can also be Deco X50-POE, but if you don't need wall/celining mounting it you can also choose from Deco X50 and Deco X55.
Also, I think Deco X50/X55 may not be sold in single units. Deco X50-POE are. Which means, if you need just one Deco ceiling mounted but three Deco in total, you could get 2-unit set of X50/X55 and single X50-POE.
An additional benefit of X50/X55 over X60 is X50 and X55 have three Ethernet ports, while X60 - just two.
