Are you sure? I know the successor the T420 supports disabling the graphics. I dont think my 410 ever had it though. It’s under display settings in the bios. Not sure about dell though, they might not have had it.
Lenovo’s bios simulator sadly only goes as old as the T530. But it’s config > display > graphics device.
It is an option to play around. But for audio production you really don’t want to be trying to use a VM unless you’re fiddling with USB passthrough (which is a pain). Audio latency on Windows is bad enough, adding Linux’s on top is awful.
