Lenovo ThinkPad T15 - UEFI only as other options greyed out

If for whatever reason you require Legacy Mode this is how you change the setting.

Kernal DMA Protection is switched on by default for security. Turning it off will allow you to change to Legacy Mode but the laptop will be open to external attack. VERY VERY VERY slim chance you'd be attacked using this method, as people would need physical access to the laptop but just so you're aware.
