You can access the information directly from Windows Disk Management, especially for disks you're not booting from. Alternatively, you can use the Diskpart command in a command prompt. Are there any files or data on the disks you wish to retain?

Turn off the computer and insert or connect a Windows installation DVD or USB installer flash drive.
Power on the machine and press the key that brings up the boot menu—likely F, though it may differ depending on your motherboard. You might need to search online for the correct key.
Choose the Windows installation DVD or USB from the boot menu and press Enter.
On the Windows Setup screen, press Shift + F10 to open a Command Prompt window.
In the Command Prompt, enter diskpart and press Enter.
Type list disk to find the disk you wish to reformat, then press Enter.
Select the desired drive using select disk # (replace # with the actual number) and press Enter.
Be extremely careful to pick the right disk.
Type clean and press Enter.
Enter convert gpt to finish the process.
Press Exit and press Enter when prompted.
Close the Command Prompt. If installing Windows, proceed with the Windows Setup process.

Hardware specifications are available.
Windows 11 demands certain hardware capabilities.
If you switch your drives to GPT and your system lacks UEFI support, it won't boot.
UEFI is necessary.

Nothing on the disks that I don’t want to lose. Should I also convert the disk I’m not booting from?

It's probably just a strange reason to keep using MBR, though I don't really understand why on a Windows PC.

I activated secure boot and set it to Windows UEFI in the BIOS. However, the PC still displays that secure boot isn't enabled. I haven't performed the mbr2GPT process yet.
