How to switch to amd gpu

I have kali linux 2022.2, KDE Plasma. I got 2 gpus: intel integrated and amd radeon 520. Kali sees the second one, cause if i run this command:

sudo lshw -c video

i get

but it runs only intel graphics, cuz in settings, in about this system i see:

i have found something on the internet, but got no idea how to do that and not sure that it will work, cuz it was on older versions
pls help me

HEY, MODERATOR, APPROVE THIS

Can anybody finally reply to this, or not?

Your post has been approved for a while. I unfortunately can't be much help as I don't have AMD, so it is up to anyone who might see your post and know how to help.

I've only had these issues when running Kali on my Macbook Pros because like you, they have dual Graphics set up, so the fix I would assume would be the same..

edit /etc/default/grub and change the following line from
GRUB_CMDLINE_LINUX=""
GRUB_CMDLINE_LINUX="intel_iommu=off"
Then save and run
update-grub
