Look in Assets\XML\GlobalDefinesAlt.xml in the directory where you installed the mod

ok but how exactly do you toggle these, for those of us without technical knowledge.

Well, I didn't define them myself, so I can't give miuc specific advice. Check the context. On/Off switches tend to be 0 = off, 1 = on. Max values are usually just numerical values.
You're looking for the numerial values inside the <iDefine stuff, e.g.
<Define>
<DefineName>DCM_RANGE_BOMBARD</DefineName>
<iDefineIntVal>1</iDefineIntVal>
</Define>

I believe the reason they are disabled is because some of the DCM components are known to be buggy and cause CTDs (stack attack for example). I suspect the settings released are the ones known to be most stable. I, however, have enabled some (air bombing missions, opportunity fire), and am playing to see if they are stable. Haven't had any problems yet.
