[Request] Thinkpad E14 - Unlock DVMT settings or set default DVMT to 64M

[ly4dsg]

Hi, I tried to build hackintosh on my Thinkpad E14 (20RA). But due to the locked DVMT settings, I can only get a 2k resolution output on my 4k distply.
Please help me to unlock DVMT settings or just set the default DVMT to 64M. Many thanks!
