I'm working on an Acer Nitro 5 515-43 with a dedicated Nvidia gtx 1650 and an integrated AMD gpu.
I want to use the dedicated gpu all the time. However the system uses the integrated one instead. What can i do to change this?
Since the integrated gpu is and amd one, the optimus/prime solution shouldn't work.
Here is some additional information about the gpus:

The driver of the nvidia gpu is:
nvidia-detector
nvidia-driver-440
The OS:
lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 20.04 LTS
Release: 20.04
Codename: focal
The kernel:
uname -rm

When i run nvidia-xconfig with root privileges and reboot afterwards i cant get past the initial logo. Only rebooting in recovery mode and deleting /etc/X11/xorg.conf with a subsequent reboot allows to use the pc again.
