Hello and welcome,
Thank you for providing mhwd output.
But system info is usually best served with an inxi (as well as mhwd);
inxi -Farz
That way we would know more about the system.
So you have a hybrid system.
Are you running davinci with prime-run (AKA - on the nvidia)?
You have options available in mhwd and/or manjaro-settings-manager GUI to be on either of the following;
video-hybrid-intel-nvidia-prime
video-hybrid-intel-nvidia-470xx-prime
Which correlate to the nvidia and the legacy nvidia-470 respectively. With the latest nvidia on Stable branch being version 550.144.03-1.
In order to get a newer nvidia driver you must either wait for updates to come to Stable branch or switch to Unstable where the latest nvidia version is currently 565.77-8.
