I have a Samsung Tab 6 with a very nice 8" oled screen. I want to use it in combo with my Bluetooth controller for my Steam Games (for a little more reading room). I've tried Steam Link and it works, but the lag of my wifi make it quite unplayable so, since i already have a dock and an hdmi cable, i was thinking of buying a second dock ( as the one in the photo). Anyone has done anything similar? Can you suggest any free android app to do the mirroring from the deck to my tablet??

Most of the external portable screen projects I've seen for the deck use devices that can directly receive video over usb-c, like XR glasses or portable screens. I don't know of a good way to convert video over usb-c (or hdmi from a dock) into something that your Android tablet can receive and play. There are some windows only apps that can stream video via usb to a tethered tablet, but I don't know of a linux/steamOS compatible option. If anyone does, I would love to hear it.

The easiest thing to try next would be to install Sunshine on your deck, and Moonlight on your tablet. It will still streamed over wifi, but a lot of people get better stream quality/less lag than with steam streaming.
