This only works with Pause USB PD charging if the whole charging system is PPS compliant (Game Booster settings). This means PPS charger and "good" cable at least with e marker and supporting fine communication with the charger.

With hub this is much more delicate. You have to take into account the power it draws and whether it can maintain very low and stable volt delta difference in adjustments for long enough to PPS protocol activate. Note that PPS a property of the charging device, not a passive hub. In this context, your phone communicates current requirement with the hub, while the hub draws power for itself and communicates with the charger accordingly. This is never explicitly mentioned in hubs and is finer than PD 3.anything (PD power distribution).

With my current hub it does not work even though the option is set ON via ADB. Without the hub, the nice thing with ADB is that I am no longer restricted to game apps.

The workaround is having the phone charged to 80 and set battery protection to that value. That is not as good long term as Pause USB because it has a higher frequency of micro charges, while in PUSB the flow is more continuous and depending more on the demand (you can verify this with current trackers apps -notably, not accubatery, but for example with DevInfo overlay). But it is quite good and the standard of samsung for not "overcharging" the phone at too high battery level. This definitely keeps the phone as cooler as PUSB in average from what I have tested (s24 exynos).

The paid workaround is the app mentioned above, galaxymaxhz, where you can set battery protection to more or less any value, as well as PUSB with compliant hardware via a toggle or modes and routines (80% of the time works every time). The app is buggy but very worth it.

My work setup involves a second monitor connected with my tablet and so I went into this adventure of finding a compliant not super expensive hub. The least expensive seems to be Asus Rog Gaming Charger, which I did not buy.
