Hi, I've recently purchased a notebook: ASUS TUF Gaming FX505DT. Which has:
AMD Ryzen 5 Mobile 3550H / 128MB ATI AMD Radeon Vega 8 Graphics / 4095MB NVIDIA GeForce GTX 1650 under Win10 version 20H2 (OS Build 19042.804)

The thing is I managed to install NVIDIA drivers, but I can get it to be the default and primary driver in the computer.

I can see both graphic devices appear correctly in DxDiag

Advanced display settings show Vega 8 as display device

If I disable Vega 8 Graphics from Device Manager... everything becomes a little laggy, lose changeresolution possibility, etc. and Advanced display settings doesn't show NVIDIA gpu as display device

NVIDIA Driver is 461.40-notebook-win10-64bit-international-dch-whql.exe
Also downloaded drivers in Asus site and didn't work.

Display Driver Uninstaller's Clean and reset of NVIDIA GPU, reboot and reinstall same NVIDIA driver as above, results the same.
In NVIDIA Control Panel 3D settings --> "Global Settings" Tab --> Prefered graphics processor, "High-Performace NVIDIA processor" is chosen.

I'm really stuck, here an Imgur album in case you want to check anything:

Thanks in advance!

At last count you have post the same question on at least six other forums and have ongoing threads on at least three of them.

Closing this thread so that members are free to help those not already receiving multiple assistance elsewhere.

Edit to add: manteca2 has advised via PM that the solution below worked for them, thanks for the information manteca2.

The primary GPU will always be Vega 8. Power hungry apps should be manually assigned to use Nvidia GPU.

If you want to, you could enable Turbo mode when needed in Armoury Crate.

its better to use Radeon Vega 8 while idling or office work, less heat and power efficiency.

If you connect your laptop to any external display via the HDMI port, then your GTX should be the display device for the external display. If your games are running by default on the integrated Vega 8 IGPU then you can change it by Right Clicking on the desktop > display settings > graphics settings > then under Graphic performance preference browse your game > select it and then click on options and then select 'High Performance'. This should let you run games on your GTX 1650.
