Disable Power Delivery charging over any of the TB4 ports on Predator Triton 17X

Does anyone know how to disable the PD charging over TB4 port on a Triton 17X when the barrel charger is also connected?
Unfortunately there is absolutely no way in Windows or in the BIOS for that matter to do that, which means that when using an external dock with PD capability, its PD will take precedence over the OEM charger, giving a much weaker charge at around 90W, instead of 330W as the OEM charger.

I've raised a support ticket with Acer and they didn't even know about the issue. Also, latest BIOS, i.e. 1.07 still doesn't solve this problem.

Please help as I cannot use any external PD-capable device without lowering the charge to the PD device's output power.

    I believe that Acer latest BIOS gives preference to power adapter barrel charging over USB-C charging, confirmed by reports on this forum but I am not sure what that protocol is for USB-C docking stations. Have you tried connecting the "Brick" power adapter FIRST and then dock the laptop?

    As I said, there is no option in the BIOS to change that behaviour unfortunately, not even in the latest one available, i.e. 1.07.

    It is an odd behaviour as Windows is clearly showing an exclamation mark on the battery icon and saying 'Weak charge' while having the PD-capable dock plugged in, however, in Predator Sense, I have the option of setting 'Performance' and 'Turbo' modes, which are disabled as soon as the the barrel charger is unplugged. When that happens, Predator Sense also issues a notification saying 'USB-C charge detected'.

    While setting 'Turbo' mode in PS, I'm definitely getting the expected performance from the laptop. As an example, around 21600 points in 3DMark TimeSpy, which is definitely in-line with the RTX 4090 mobile performance.
