GNU/Linux Debian 11 nvidia-drm driver errors (version 460.73.01)

Hello, I’m currently using an Nvidia GeForce GTX 1660 Ti with proprietary drivers on my laptop (+ Intel GPU, PRIME render offload enabled and functional) and systematically at boot time, I get the following errors:

I’m currently running a 5.10.28 custom kernel, but I also had the errors with the previous (Debian mainstream) kernel.

Please use options nvidia-drm modeset=1 and build initramfs again to see if it fixes issue.

Hello, I used a file in /etc/modprobe.d in order to apply modeset=1 at boot time and did update-initramfs -u but after reboot the issue is still there.

$ sudo cat /sys/module/nvidia_drm/parameters/modeset 
Y
$ sudo dmesg |grep nvidia
