[BUG] Unable to compile firmware with UBL enabled - i3 Mega S with TMC and BMG

[Ekodas]

I have an i3 Mega S with TMC drivers, DGUS 2 screen, BMG extruder, and BL Touch installed on Pin 4 using UBL. I have previously modified and compiled custom firmwares from version 1.16 through 1.3.0 with no problems. Starting with 1.4.0 and also with 1.4.1, I am unable to compile firmware as soon as I enable UBL. I have everything configured in my configuration.h and configuration_adv.h files the same as I had them with 1.3.0. If I leave it set for bilinear leveling, the firmware will compile. However, as soon as I disable bilinear and activate UBL, I receive the following error at the very end of compiling:

Since UBL heavily relies on a fully working smart display controller (Like 2004 or 12864) this firmware is not intended to use UBL in the first place.

I can take a look, but to be honest... that's not a bug, because it's not supported at all.
