This concerns a hybrid setup with an AMD Radeon RX640 2 GB DDR5 64 2GB DDR5 next to a built in Intel GPU. Whatever I try (tried every trick available on Youtube, tried every driver, tried disabling Intel GPU, whaterer) there is no way in triggering the AMD GPU to work as encoder or decoder. Adobe Premiere works nicely together with the GPU. As does every other running software I have. Not so for PD365.

Any idea on this?

The hybrid solution that you have is made for gaming but is a waste of money for video editing. The laptop screen itself is hardware wired to the intel GPU. That Intel GPU can pass 3D elements from the discrete GPU (from 3D games), but it is not made to pass the hardware decoding/encoding from the AISC bloc (that is separated from the 3D cores).
Now, there are professional editing laptops that have a mux (a switch) between the laptop screen and the iGPU + dGPU and those can make use of all the blocks in the dGPU completelly.

PS: Adobe Premiere doesn't use the AMD GPU for encoding in your laptop, it uses the Intel QuickSync one.

According to this AMD site if your laptop has switchable graphics then here is a procedure: https://www.amd.com/en/support/kb/faq/dh-017 .

That doesn't work, AMD "switchable graphics" is equal to nvidia's Optimus.
My AMD laptop has that and works only for 3D cores (gaming) but not for their hardware video encoding engine. Naming of that ASIC block changed in the newer chips to Video Core Next, but it is still separated from 3D cores.

The only way to check for that mux is to enter in the BIOS, and see if there is an option to disable iGPU, leaving visible in Windows system only the dGPU (AMD).
