HDMI not working with Lenovo Legion 5 Notebook

I’m having problems getting an external monitor to work over HDMI on my new Lenovo Legion 5 Notebook. I’ve gone through registering the nvidia driver with mokutils as per the openSUSE SDB:NVIDIA_Drivers page but, so far, no success.
According to the page running lsmod | grep nvidia should show something like

nvidia_drm             57344  2
nvidia_modeset       1187840  3 nvidia_drm
nvidia_uvm           1110016  0
nvidia              19771392  81 nvidia_uvm,nvidia_modeset
drm_kms_helper        229376  2 nvidia_drm,i915

What I get is:

video                  69632  3 nvidia_wmi_ec_backlight,amdgpu,ideapad_laptop
wmi                    45056  4 video,nvidia_wmi_ec_backlight,wmi_bmof,ideapad_laptop

Does this mean the nvidia drivers aren’t loaded?
I’m out of my depth here so any help would be appreciated.

OK, I’ve managed to get this working.
I disabled secure boot (which I’m not exactly happy about) which got lsmod showing the modules as per the SDB page .
This didn’t start the HDMI but running prime-select next-boot nvidia has now brought up the external monitor after a reboot.
Interestingly, despite the next-boot argument, the system now always reboots to nvidia

@fudokai as a Tumbleweed user you should be following the Factory Mailing list… it’s a known issue with the new kernel and lockdown patches.

The Factory Mailing List is a new one on me - I’ll check it out although it’s probably a bit too technical for me.
Hopefully a new kernel upgrade will sort things out and I can revert to secure boot.

@fudokai not really, but will give you insight as to how/why etc. https://lists.opensuse.org/archives/list/factory@lists.opensuse.org/thread/APEWGMWSEABQ5ZFGZ2I5M3MWJERZ4K7I/

You can also get a heads up on changes that may affect you before they arrive, like the lockdown patches.
