Cannot disable CSM to enable Secure Boot

Winver. 22H2 19045.3208 Hi there, I am having difficulty in enabling Secure Boot even when it is supported with my motherboard on the ASUS website. I was made aware of this by using the PC Health app:

After a bit of research, CSM being enabled in the BIOS can be a reason why Secure Boot is showing up as Unsupported on my msinfo32 report:

However, I cannot disable CSM on my pc as it does not boot Windows 10 after the change, meaning that either something in my pc does not have a UEFI driver or that it is due to my primary disk being MBR and not GPT (according to research). Any help with potential fixes or suggestions is much appreciated, thank you

Thank you for the suggestion, I'll try and see what I can do about changing the disk to GPT and hope that works...

 

Disabling CSM and enabling secure boot makes my Boot drive disappear.

Windows 11 upgrade requires I enable secure boot on my PC, it's main use is as a home Plex Server, It has an Intel 8700k and I just use the integrated graphics UHD 630, I don't need a discreet gpu for this. I believe W11 supports this.

In the BIOS (gigabyte z370 motherboard) the Storage Boot Option & Other PCI Devices are set to UEFI mode.

To enable 'Secure Boot' I have to disable CSM support, which I do and enable secure boot but when my PC reboots it goes back to set up and there is no boot drives listed, I have to return the bios back to the original for my drives to show up, the Boot drive is a nvme Samsung 980 pro.

Can anyone tell me what I am doing wrong?

Thx.
