That's why I said to add it. 

Click on the + sign on the right and then manually enter in the info as in the screenshotECDV.png

Doesn't matter, all Dell requires this patch for Catalina. Won't be an issue for Mojave or HS with that added patch either.

If you search your raw DSDT for Embedded Controller, what ever name it is, rename it to EC

Example, some system has H_EC, others has EC0, for Dell it's named ECDV, they all will have to be rename to EC like on a real Mac.

Post the error screenshot and the Config file.

Make sure to boot with verbose + debug 0x100 mode
